ABSTRACT
The study investigated the perceived impact of OPAC on effective retrieval of information resources by postgraduate students in Benue State University, Makurdi. The study looked at the perceived impact of OPAC on effective retrieval of information resources, purpose of utilizing OPAC by postgraduate students, search strategies used by postgraduate students for effective retrieval of information resources, challenges as well as strategies to enhance the use of OPAC by postgraduate student for effective retrieval of resources. Five (5) objectives with corresponding research questions guided the study. The study adopted descriptive survey research design. The population of the study was made up of 38 postgraduate students who are registered with Benue State University Library. However, the census sampling was adopted for the study due to the small nature of the population. The instrument for data collection was self-structured questionnaire titled “Perceived Impact of OPAC on Information Retrieval Questionnaire” (PIOPACIRQ) which was validated by experts and a reliability coefficient of 0.947 was obtained. Data was collected and analyzed using frequent count and means. Findings of the study revealed that, there is a high perceived impact of OPAC on effective retrieval of information resources by postgraduate students in Benue State University, Makurdi. Finding also revealed that, postgraduate students in Benue State University, Makurdi utilize OPAC for various purposes such as to know the available resources in the university library, to locate books by author, title and subject, assists in obtaining books from the university library, among others. Finding also revealed the search strategies used by postgraduate students for effective retrieval of information resources in Benue State University Makurdi to include by author, title, subject and edition. The study further revealed the challenges hindering the use of OPAC for effective retrieval of information resources in Benue State University, Makurdi to include: lack of skilled library professionals to assists students, lack of orientation from library staff, lack of time to retrieve the vast information, slow internet connectivity speed, among others. Findings finally revealed some key strategies to enhance the use of OPAC for effective retrieval of information resources by postgraduate students in Benue State University, Makurdi which include: employment of skilled/competent library staff, need to design user-friendly OPAC template, improvement of internet connectivity speed, and organizing user education program to orientate postgraduate students on the use of OPAC, among others. Recommendations were also made based on the findings of the study.

AbstractResearch methods play an extremely important role in studies. Statistical methods are fundamental and vital for quantitative research. The authors of this paper investigated the research papers that used statistical methods including parametric inferential statistical methods, nonparametric inferential statistical methods, predictive statistical correlation methods, and predictive statistical regression methods in library and information science and examined the connections and interactions between statistical methods and their application areas including information creation, information selection and control, information organization, information retrieval, information dissemination, and information use. Both an inferential statistical method and graphic clustering visualization method were employed to explore the relationships between statistical methods and application areas and reveal the hidden interaction patterns. As a result, 1821 research papers employing statistical methods were identified among the papers published in six major library and information science journals from 1999 to 2017. The findings showed that application areas affected the types of statistical methods utilized. Studies in information organization and information retrieval tended to employ parametric and nonparametric inferential methods, while correlation and regression methods were applied more in studies in information use, information dissemination, information creation, and information selection and control field. These findings help researchers better understand the statistical method orientation of library and information science studies and assist educators in the field to develop applicable quantitative research methodology courses.

Full textAbstract:
The survey aims to investigate distance students’ perceptions of the efficacy of the online catalogue as a tool for information retrieval at the University of Zambia. A survey research design has been adopted in the study. Convenient sampling method was used to select 160 distance students. A structured questionnaire was developed and distributed to undergraduate distance students. The Statistical Package for Social Sciences (SPSS) software was used to analyse quantitative data into frequencies and percentages. The study established majority of distance students rarely used the online public access catalogue in exploiting the resources in the university library. Instead they employed shelf-to-shelf browsing in information searching and retrieval skills. Lack of proper orientation and user education were identified as major factors militating against their maximum utilization and exploitation of the resources in the university library. The findings of the study will inform stakeholders on how best to turn around the negative trends of OPAC.

Full textAbstract:
There are a number of research projects at present underway at the School of Information and Media in Aberdeen. The School, with an established portfolio of courses in information, library studies and publishing, has recently grown through the incorporation of communications and modern languages
teaching staff. The growth of the School from 10 academic staff four years ago to a current position with
approximately 50 academic and research staff, is reflected in a corresponding growth in research activity and in the range of research interests represented. New course development, in particular the Postgraduate Diploma/MSc in Information Analysis, has also fuelled the research effort. Following the last Research Assessment Exercise, a policy decision was taken to invest much of the funding achieved in the
appointment of Research Assistants who could support the development of research initiatives in the School. The mix of research interests is reflected in the establishment of four research clusters, which seek to draw together staff working in broadly related areas, in order that they may share experience and develop best practice. These clusters focus on information management, information technology/information
retrieval, education for information, and publishing and mediation of information. Some of the groups are
large, boisterous and possibly hyperactive: others are smaller and more recently established. It might be intere sting to ponder the most effective size and orientation of such groups for maximizing produclivity and enhancing quality, but that is an issue for another day. This article briefly describes the activities and interests of each of the clusters.

Abstract
Objective – To determine the extent to which embedded librarianship is understood and implemented with a focus on service models, best practices, and barriers.
Design – Survey questionnaire with follow up interviews.
Setting – Provincial and ministerial university libraries in China.
Subjects – Subject or liaison librarians from the 84 institutions with science and technology “information searching and evaluation centres” called S&TNS (p. 56).
Methods – The authors identified potential participants through the eligible institutions’ library websites or by contacting the library’s managers. Then they randomly selected three librarians (n = 252) from each library to be invited to participate. 56 responded from 41 unique institutions. When respondents indicated that their library had embedded library services, the authors contacted them for follow up interviews.
Main results – Results of the questionnaire revealed that most respondents were unclear about the concept of embedded librarianship with many mistaking traditional models of librarianship as embedded. Roughly half (n = 21) of respondents reported embedded librarians at their institution.
Follow up interviews revealed five models of embeddedness: (1) subject librarianship, (2) teaching information retrieval or library orientation sessions, (3) participation in research teams, (4) co-location with academic departments, and (5) assisting university administration with decision-making. Only half of these libraries (n = 11) conducted some form of assessment.
Conclusion – Embedded librarianship is a promising, but not yet widely adopted model in Chinese university libraries. More should be done to advocate for its implementation or libraries risk obsolescence.

Full textAbstract:
PurposeThe focus of this study is the development of effective user education programs that will enhance the use of electronic information resources (EIR) in an era of electronic information for the students of the University of Agriculture, Abeokuta, which consequently could be adapted for students in other higher institutions of learning.Design/methodology/approachThis study was carried out during the first semester of the 2010/2011 academic session (November 2010 to February 2011), employing a survey method. The target population is postgraduate students (postgraduate diploma, Master's degree and Doctor of Philosophy students) of the seven colleges that run postgraduate programs at the University of Agriculture, Abeokuta. Of a total population of 330 postgraduate students, 250 postgraduate students were selected randomly using a purposive sampling technique since the student population was not evenly distributed across the colleges. Administration and retrieval of the questionnaire lasted for six weeks.FindingsThe findings of this study have shown that the user education program of Nimbe Adedipe Library is not adequate; the library provides more library orientation than bibliographic instruction and information literacy skills. It was also found that few of the students received training on EIR usage while an analysis of the open‐ended questions revealed that the students got to know how to use electronic resources through their own efforts, periodic training in the library, and through the efforts of some library staff and friends. It was also found that use of EIR has a great impact on the respondents' academic activities, as reflected in their responses, where the students agreed that their academic work would suffer without the use of EIR.Practical implicationsIt is the belief of the researchers that empirical research on the use of library resources is crucial for the design and implementation of user education programs.Originality/valueThe results of this study will be a meaningful addition to the literature of library and information science in the area of user studies.

Full textAbstract:
Purpose Online calendar services (OCS) are primarily used for temporal orientation and reminding. Nonetheless, calendar work may also entail generic activities such as scheduling, tracking, archive and recall and retrieval which are not adequately supported by available systems. The purpose of the paper is to explore how online calendaring may be re-configured and re-aligned to alleviate these shortcomings, thus servicing accountability in team work and flexibility in organizational routines. Design/methodology/approach Following a design science research methodology, the authors review “justifiable failures” or deliberate non-use of OCS and establish the rationale for, design and evaluate a digital service that configures calendaring as an ecology of separate digital materials supporting file-, photo- and video-sharing services, online argumentation, project/task management and social bookmarking. The new service is a digital composite of materials that incrementally co-adapt and co-evolve to serve primary and secondary work-oriented activities. The authors assess the value of the digital composite in two empirical settings and discuss intrinsic features that create new possibilities for action. Findings The authors present the rationale, design, implementation and evaluation of a new digital composite calendaring service which is deployed in two empirical settings, namely group vacation planning and collective information management. Each case features different re-configurations of calendaring to serve human intentions. In vacation planning, the digital composite of the calendar operates as a mashup allowing peers to negotiate, schedule and track vacation options and archive, recall or retrieve digital memories of vacations. In the case of collective information management, the digital composite is further augmented so as to re-align performative and ostensive aspects of routines in a regional organic farming partnership. Practical implications Digital composites rely on the interdependent operation of different bounded systems and services to establish configured ecologies of (previously) separate digital artifacts. The practical implications of digital composites are that they can appropriate performative capacities which are already established and embedded across different settings. As a result, they enact complex digital assemblages which can re-align not only daily activities but also organizational routines. On the other hand, digital composites remain in flux, since their state, at any moment in time, is partly determined (even temporarily) by the state of their constituent parts. Originality/value Calendaring as presented in this paper defines a genre of digital artifacts that promote flexible and accountable collaborative work while exploiting material agency and resources distributed across digital settings. As such, it establishes a kind of meta-material that invokes collective social agency, thus re-aligning performative and ostensive aspects of organizational routines.

Full textAbstract:
Library catalogue or inventory book is one of the most important sources for exploring its stock development, collection creation strategy, content of documents. Catalogue contains a lot of information about content of collections, quality and quantity aspects, and enables reconstruction of libraries which had been closed, dispersed or damaged by various disasters. Catalogues of old, especially non-operating libraries can also play role of reflections of scientific, cultural, social life of certain historical period, sometimes even of witnesses of the whole epoch. This historical source is very important for history of book and library. Their analysis can fill gaps in research of cultural communication of certain periods. Library catalogue is an information search system giving better orientation in the library to the reader, satisfaction of his informational needs and expectations. Exploring of library catalogue can be multiform depending on the subject and object of the exploration. Scientific researches of library catalogues are not popular; they are rather additional source of book history. The old catalogues give possibility to reconstruct traditions and culture of forming catalogues of that time, retrieve regulations and specifics of their forming. The article reveals content of catalogues of institutional, personal libraries of 19th-20th centuries preserved in the Rare Book and Manuscript Department of Martynas Mažvydas National Library of Lithuania, their provenance attributes and physical features, making emphasis on Lithuanian books in these libraries. These are catalogues or lists of books owned of Samogitian Seminary, Ateitininkai Chapter established by Lithuanians who moved to Voronezh (Russia) during the 1st World War, The Januškevičiai (progenitors of the Dobužinskiai family), explorer of Lithuanian language Kazimieras Jaunius. These catalogues were selected from library catalogues of the National Library, because the institutions and persons mentioned were important for Lithuanian history and culture. Old library catalogues present evidence what important sources they can be for exploring of various historical stages of the country, historical and cultural heritage of various institutions, organizations or personalities, cultural and informational communication, distribution of a certain book, its popularity in libraries of various levels, culture and traditions of library catalogues forming during the certain time period.

Full textAbstract:
Libraries acquire and facilitate access to electronic information resources that support core functions of universities they serve. Despite substantial investments by universities in infrastructures and resources to facilitate access to electronic resources, studies have revealed that these resources are at times not optimally utilized as expected. Network literacy is defined as the knowledge of web-based information resources, ability to effectively use ICT tools to access resources available online, ability to judge the relevance of information retrieved, and capability to use computer-mediated communication tools to manage or utilize the accessed information. The purpose of this study was to assess network literacy and utilization of electronic resources among Kabarak University students in Kenya and consequently provide some insight into usage of networked resources at the university. Objectives of the study entailed assessing users’ awareness of internet applications and utilization of electronic resources; assessing users’ awareness of Social Networking Sites (SNS) and utilization of electronic resources, establishing the levels of user awareness of electronic resources available at Kabarak University, evaluating users’ competencies in using electronic resources and establishing challenges encountered in utilizing electronic resources at Kabarak University. The study was anchored on the Digital Library model that depicts users’ interaction with networked environments, taking into consideration the various systems involved. The study was undertaken at Kabarak University main campus library. Stratified sampling was used to segregate students and librarians whose opinions were also sought on matters covered by the study. Simple random sampling was used to select students for the study while purposive sampling was employed to select resourceful librarians for the research. The study adopted a descriptive research design and used an approach where qualitative and quantitative data were gathered using a set of structured questionnaires that contained open and close ended questions based on objectives that guided the study. The questionnaires were first pilot – tested at Moi University Eldoret Town campus to determine their validity and also subjected to Cronbach’s Alpha reliability test to determine that acceptable internal reliability levels were attained. These questionnaires were then directly issued to the selected respondents. Analysis of the collected data was done using the Statistical Package for Social Science (SPSS) software version 23 and thereafter, responses arranged in themes as appropriate. Frequencies and percentage distributions were used to highlight patterns in the data and facilitate interpretation. Among the findings was that students were aware of existence of electronic resources though some of them were not aware of what these electronic resources entailed specifically, and that among the greatest challenges they faced in using the electronic resources were slow internet connectivity speeds and inadequate points of accessing the internet. The study also established that the library relied majorly on orientation to sensitize students on electronic resources. Reinforcement and regularly conducting orientation programmes were recommended as a means of promoting network literacy at the University.

Purpose This paper aims to establish the level of use of the electronic resources at the University of Venda, which is one of the previously disadvantaged universities in South Africa. It identifies the different electronic resources used at the university, determines the level of awareness and training in the use of these resources and suggests ways in which electronic resources may be enhanced. The rapid changes in the information and communication technology (ICTs) have influenced service delivery in academic libraries in terms of how information is gathered, accessed, retrieved and used. Hence, electronic resources are invaluable research tools in academic libraries in the twenty-first century. Design/methodology/approach A qualitative research methodology was adopted, and semi-structured interviews were conducted with each participant to get in-depth information. The target population was all third-year students registered with the School of Human and Social Sciences at the University of Venda. The third year undergraduate students from this particular school where chosen because statistics revealed that these students where ranked among the top in the use of computers. Findings The findings revealed that the level of usage of these resources by undergraduate students is elementary and limited to SABINET and EBSCO host. Undergraduate student’s level of awareness of the different electronic resources is low. They confused electronic resources to Web-based internet sources. It also revealed that the level of awareness and training in the use of these resources is still generic, as training is mostly a once off orientation at the first year. Research limitations/implications This paper focuses on third year undergraduate students who were using computers because the researchers were interested in finding out whether students using computers were also using electronic resources. It excluded other profiles such as age, gender and computer usage behaviour of electronic resources. Practical implications Adequate use and knowledge of electronic resources at universities is instrumental towards realisation of the country’s ICT Strategy and the outcome-based education (OBE) model of teaching movement. Suggestions are made to the university, the university library, university librarians and the Library Association of South Africa on how to enhance the use of electronic resources. Originality/value It establishes the level of use of electronic resources in one of South African historically disadvantaged universities, a point of contact to other previously South African disadvantaged universities and make suggestions on how electronic resources may be enhanced. It adds to the body of knowledge on the use of electronic resources in academic libraries in South African universities.

Purpose – The paper aims to develop a new method for potential relations retrieval. It aims to find common aspects between co-occurrence analysis and ontology to build a model of semantic information retrieval based on co-occurrence analysis. Design/methodology/approach – This paper used a literature review, co-occurrence analysis, ontology build and other methods to design a model and process of semantic information retrieval based on co-occurrence analysis. Archaeological data from Wuhan University Library's bibliographic retrieval systems was used for experimental analysis. Findings – The literature review found that semantic information retrieval research mainly concentrates on ontology-based query techniques, semantic annotation and semantic relation retrieval. Moreover most recent systems can only achieve obvious relations retrieval. Ontology and co-occurrence analysis have strong similarities in theoretical ideas, data types, expressions, and applications. Research limitations/implications – The experiment data came from a Chinese university which perhaps limits its usefulness elsewhere. Practical implications – This paper constructed a model to understand potential relations retrieval. An experiment proved the feasibility of co-occurrence analysis used in semantic information retrieval. Compared with traditional retrieval, semantic information retrieval based on co-occurrence analysis is more user-friendly. Originality/value – This study is one of the first to combine co-occurrence analysis with semantic information retrieval to find detailed relationships.

Full textAbstract:
The author reviews in brief the library catalogs as the origins of subject search in the modern search systems. He examines the concept of “subject search”, offers its definition (lacking in the state standards – GOSTs), specifies the types (subject search, search by keywords, systematic search) and characterizes them. The libraries use intensively all three types of subject search while the Internet-based search engines offer just one type, i.e. search by keywords. The universal search systems, like Google and Yandex, do not entail cataloguing, however the possibility of subject search by keywords is designed within html-code and tagging system. The author investigates into the application of systematic search on the Internet. He concludes that this search type emphasizes is intensively applied to the resources related to libraries or science and research (library e-catalogs, abstract databases, etc.). He suggests that in time tagging, the Internet popular subject search system, will tend to classifying and systematic search.

Microcomputer technology has had a tremendous effect on the way information and research in education can be retrieved. Since the early 1960's and the availability of online computer searching of the ERIC database, about thirty U.S.-produced databases specifically oriented to educators have become available. Microcomputer technology makes direct access possible to these databases by anyone with a microcomputer, modem, and printer. Such direct access means that educators who have not had the opportunity to use library computer search services may now conduct their own online, interactive searches of the vast body of published literature and other products of educational research and practice. This article identifies and describes many of the educational databases and the information retrieval companies that offer information search services for educators.

Objectives – To compare the performance of the vector space model and the probabilistic weighting model of relevance feedback for the overall purpose of determining the most useful relevance feedback procedures. The amount of improvement that can be obtained from searching several test document collections with only one feedback iteration of each relevance feedback model was measured.
Design – The experimental design consisted of 72 different tests: 2 different relevance feedback methods, each with 6 permutations, on 6 test document collections of various sizes. A residual collection method was utilized to ascertain the “true advantage provided by the relevance feedback process.” (Salton & Buckley, 1990, p. 293)
Setting – Department of Computer Science at Cornell University.
Subjects – Six test document collections.
Methods – Relevance feedback is an effective technique for query modification that provides significant improvement in search performance. Relevance feedback entails both “term reweighting,” the modification of term weights based on term use in retrieved relevant and non-relevant documents, and “query expansion,” which is the addition of new terms from relevant documents retrieved (Harman, 1992).
Salton and Buckley (1990) evaluated two established relevance feedback models based on the vector space model (a spatial model) and the probabilistic model, respectively. Harman (1992) describes the two key differences between these competing models of relevance feedback.
[The vector space model merges] document vectors and original query vectors. This automatically reweights query terms by adding the weights from the actual occurrence of those query terms in the relevant documents, and subtracting the weights of those terms occurring in the non-relevant documents. Queries are automatically expanded by adding all the terms not in the original query that are in the relevant documents and non-relevant documents. They are expanded using both positive and negative weights based on whether the terms are coming from relevant or non-relevant documents. Yet, no new terms are actually added with negative weights; the contribution of non-relevant document terms is to modify the weighting of new terms coming from relevant documents. . . . The probabilistic model . . . is based on the distribution of query terms in relevant and non-relevant documents, This is expressed as a term weight, with the rank of each retrieved document then being the sum of the term weights for terms contained in the document that match query terms. (pp. 1-2)
Second, while the vector space model “has an inherent relationship between term reweighting and query expansion” (p. 2), the probabilistic model does not. Thus, query expansion is optional, but given its usefulness, various schemes have been proposed for expanding queries using terms from retrieved relevant documents.
In the Salton and Buckley study 3 versions of each of the two relevance feedback methods were utilized, with two different levels of query expansion, and run on 6 different test collections. More specifically, they queried test collections that ranged in size from small to large, and that represented different domains of knowledge, including medicine and engineering with 72 experimental runs in total.
Salton and Buckley examined 3 variants of the vector space model, the second and third of which were based on the first. The first model was the classic Rocchio algorithm (1971), which uses reduced document weights to modify the queries. The second model was the “Ide regular” algorithm, which reweights both relevant and non-relevant query terms (Ide, 1971). And the third model was the “Ide dec-hi” algorithm, which reweights all identified relevant items but only one retrieved nonrelevant item, the one retrieved first in the initial set of search results (Ide & Salton, 1971).
As well, 3 variants of the probabilistic model developed by S.E. Robertson (Robertson, 1986; Robertson & Spark Jones, 1976; Robertson, van Rijsbergen, & Porter, 1981; Yu, Buckley, Lam, & Salton, 1983) were examined: the conventional probabilistic approach with a 0.5 adjustment factor, the adjusted probabilistic derivation with a different adjustment factor, and finally an adjusted derivation with enhanced query term weights. The 6 vector space model and probabilistic model relevance feedback techniques are described in Table 3 (p. 293).
The performance of the first iteration feedback searches were compared solely with the results of the initial searches performed with the original query statements. The first 15 documents retrieved from the initial searches were judged for relevance by the researchers and the terms contained in these relevant and non-relevant retrieved items were used to construct the feedback queries. The authors utilized the residual collection system, which entails the removal of all items previously seen by the searcher (whether relevant or not), and to evaluate both the initial and any subsequent queries for the reduced collection only.
Both multi-valued (partial) and binary weights (1=relevant, 0=non-relevant) were used on the document terms (Table 6, p. 296). Also, two types of query expansion method were applied: expanded by the most common terms and expanded by all terms (Table 4, p. 294). While not using any query expansion and relying solely on reweighting relevant and non-relevant query terms is possible, this option was not examined. Three measures were calculated to assess relative relevance feedback performance, the rank order (recall-precision value); search precision (with respect to the average precision at 3 particular recall points of 0.75, 0.50, and 0.25), and the percentage improvement in the 3-point precision feedback and original searches.
Main Results – The best results are produced by the same relevance feedback models for all test collections examined, and conversely, the poorest results are produced by the same relevance feedback models, (Tables 4, 5, and 6, pp. 294-296). In other words, all 3 relevance feedback algorithms based on the vector space retrieval model outperformed the 3 relevance feedback algorithms based on the probabilistic retrieval model, with the best relevance feedback results obtained for the “Ide dec hi” model. This finding suggests that improvements in relevance from term reweighting are attributable primarily to reweighting relevant terms. However, the probabilistic method with adjusted derivation, specifically considering the extra weight assignments for query terms, was almost as effective as the vector space model relevance feedback algorithms.
Paired comparisons between full query expansion (all terms from the initial search are utilized in the feedback query) and partial query expansion by the most common terms from the relevant items, demonstrate that full expansion is better, however, the difference between expansion methods is small.
Conclusions – Relevance feedback methods that reformulate the initial query by reweighting existing query terms and adding new terms (query expansion) can greatly improve the relevance of search results after only one feedback iteration. The amount of improvement achieved was highly variable across the 6 test collections, from 50% to 150% in the 3-point precision. Other variables thought to influence relevance feedback performance were initial query length, characteristics of the collection, including the specificity of the terms in the collection, the size of the collection (number of documents), and average term frequency in documents. The authors recommend that the relevance feedback process be incorporated into operational text retrieval systems.

Purpose The purpose of this paper is to present the initial relationship between the Classification Research Group (CRG) and the Center for Documentation and Communication Research (CDCR) and how this relationship changed between 1952 and 1970. The theory of normative behavior and its concepts of worldviews, social norms, social types, and information behavior are used to characterize the relationship between the small worlds of the two groups with the intent of understanding the gap between early classification research and information retrieval (IR) research. Design/methodology/approach This is a mixed method analysis of two groups as evidenced in published artifacts by and about their work. A thorough review of historical literature about the groups as well as their own published works was employed and an author co-citation analysis was used to characterize the conceptual similarities and differences of the two groups of researchers. Findings The CRG focused on fundamental principles to aid classification and retrieval of information. The CDCR were more inclined to develop practical methods of retrieval without benefit of good theoretical foundations. The CRG began it work under the contention that the general classification schemes at the time were inadequate for the developing IR mechanisms. The CDCR rejected the classification schemes of the times and focused on developing punch card mechanisms and processes that were generously funded by both government and corporate funding. Originality/value This paper provides a unique historical analysis of two groups of influential researchers in the field of library and information science.

Purpose – Successful information retrieval is determined by library patrons retrieving accurate, relevant, and up-to-date information stored in documents; this affects their self-efficacy, emotions, and behavior. The purpose of this paper is to examine the impact of mastery experiences, self-evaluation, vicarious observation of others’ experiences, social feedback, and physiological state of library patrons’ emotions after information retrieval. Design/methodology/approach – A structured close-ended questionnaire survey was utilized of which 200 responses were valid and usable for data analysis. Multiple regression analysis was executed to assess the influence of personal self-evaluation, comparisons with others, physiological state, and social feedback, on the library patrons’ emotions after information retrieval. Findings – The findings of this study indicated that social feedback had the greatest influence on the library patrons’ emotions after information retrieval, followed by personal self-evaluation and physiological state. Originality/value – This study employed quantitative research design utilizing multiple regression analysis which provides useful insight for university librarians on the specific factors that have significant effects on library patrons’ emotions after information retrieval. The outcomes add a new perspective to preceding studies on library patrons’ emotions after information retrieval, which has previously been inadequately researched in the Malaysian setting.

Full textAbstract:
Food-storing birds retrieve hoarded food by remembering the locations of large numbers of spatially dispersed caches. The basic patterns of spatial orientation in these animals have been established in research on two major groups of food-storing birds, chickadees and tits (Paridae), and jays and nutcrackers (Corvidae). Experiments using displacement of landmark arrays show that food-storing birds rely on visual information from nearby landmarks to locate concealed caches. The appearance of the cache sites themselves seems to be relatively unimportant in cache retrieval, perhaps because local features are subject to change during the lifetime of a cache. Under some conditions, food-storing birds use sun-compass information to orient their search for caches, but appear to integrate sun-compass information with landmark information. Lesions of the avian hippocampus disrupt cache retrieval and other spatial tasks in food-storing birds without disrupting the formation of simple associations. Comparative studies show that food-storing birds possess a hippocampus larger than that of non-food-storing birds, probably as an evolutionary consequence of their dependence on spatial orientation for cache retrieval. Experience with cache retrieval plays a role in the development of increased hippocampal size, and there are indications of seasonal variation in hippocampal size in food-storing species.

When trying to locate information on the Web people are faced with a variety of options. This research reviewed how a group of health related professionals approached the task of finding a named document. Most were eventually successful, but the majority encountered problems in their search techniques. Even experienced Web users had problems when working with a different interface to normal, and without access to their favourites. No relationship was found between the number of years' experience Web users had and the efficiency of their searching strategy. The research concludes that if people are to be able to use the Web quickly and efficiently as an effective information retrieval tool, as opposed to a recreational tool to surf the Internet, they need to have both an understanding of the medium and the tools, and the skills to use them effectively, both of which were lacking in the majority of participants in this study.

Full textAbstract:
Purpose The library orientation session is an important marketing tool because it offers the first opportunity for library staff to connect with new clients (Craft and Ballard-Thrower, 2011; Rhoades and Hartsell, 2008). This paper aims to explore library orientation practices in special libraries and information centers with the goal of surveying current practices and identifying guidance for successful orientation program design and delivery. Design/methodology/approach This study explored library orientation practices in special libraries and information services through an electronic survey. The survey questions were developed based on themes that emerged from case studies on library orientations from the academic library literature. These themes included reasons for library orientation program redesigns, the importance of partnerships in orientation design and delivery and the tools and techniques used in the delivery of orientation sessions. Findings The results revealed that library orientations are taking place in special libraries, but there is no consistent approach to library orientation delivery. Even within a single library, multiple approaches to library orientations are taken based on client availability, demand and information needs observations of library staff. Participants’ responses were analyzed to develop recommendations for special library orientations. These include developing partnerships (particularly with human resource departments), using technology strategically, considering the timing of orientations for new potential clients in relation to their start as new employees in the host organization, customizing library orientations based on client segment, engaging in ongoing outreach, and being flexible in design and delivery methods. Research limitations/implications This study represents a starting step in an exploration of library orientation practices in special libraries. The key limitation of this study was the low response rate leading to small sample size. A larger sample of special libraries would be needed to produce a quantitative analysis of the prevalence of practices with an acceptable degree of statistical significance. Alternately, smaller samples of special libraries organized by characteristics such as size or type (e.g. corporate libraries, law libraries and medical libraries) could be conducted to determine if distinctive trends exist within these special library types. Practical implications This study revealed information about key practices and challenges that can be used by special library practitioners seeking to implement or redesign a library orientation program in their library. Originality/value While academic and practitioner literature exists detailing library orientation activities in academic and school libraries, there are very few papers on special library orientations. This study fills a gap in the literature by investigating library orientation practices in special libraries and information centers.

Purpose The purpose of this paper is to clarify the conceptual issues of information behaviour research by reviewing the approaches to information interaction in the context of information seeking and retrieval (IS&R). Design/methodology/approach The study uses the conceptual analysis focussing on four pioneering models for interactive IS&R proposed by Belkin, Ingwersen and Ingwersen and Järvelin. Findings A main characteristic of models for information interaction is the tripartite setting identifying information resources accessible through information systems, intermediary/interface and user. Dialogue is a fundamental constituent of information interaction. Early models proposed by Belkin and Ingwersen focussed on the dialogue occurring in user-intermediary interaction, while more recent frameworks developed by Ingwersen and Järvelin devote more attention to dialogue constitutive of user-information system interaction. Research limitations/implications As the study focusses on four models developed within the period of 1984-2005, the findings cannot be generalised to depict the phenomena of information interaction as a whole. Further research is needed to model the specific features of information interaction occurring in the networked information environments in particular. Originality/value The study pioneers by providing an in-depth analysis of the ways in which pioneering researchers have conceptualised the phenomena of interaction in the context of IS&R. The findings contribute to the elaboration of the conceptual space of information behaviour research.

Purpose The purpose of this paper is to demonstrate how to apply traditional information retrieval (IR) evaluation methods based on standards from the Text REtrieval Conference and web search evaluation to all types of modern library information systems (LISs) including online public access catalogues, discovery systems, and digital libraries that provide web search features to gather information from heterogeneous sources. Design/methodology/approach The authors apply conventional procedures from IR evaluation to the LIS context considering the specific characteristics of modern library materials. Findings The authors introduce a framework consisting of five parts: search queries, search results, assessors, testing, and data analysis. The authors show how to deal with comparability problems resulting from diverse document types, e.g., electronic articles vs printed monographs and what issues need to be considered for retrieval tests in the library context. Practical implications The framework can be used as a guideline for conducting retrieval effectiveness studies in the library context. Originality/value Although a considerable amount of research has been done on IR evaluation, and standards for conducting retrieval effectiveness studies do exist, to the authors’ knowledge this is the first attempt to provide a systematic framework for evaluating the retrieval effectiveness of twenty-first-century LISs. The authors demonstrate which issues must be considered and what decisions must be made by researchers prior to a retrieval test.

Digital library is a library that has a collection of books in the form of digital formats and which can be accessed by computer. The digital collection is usually a collection of research, thesis, thesis, desertation and e-book. The quality of the collection is crucial to the development of digital libraries. This study uses IFLA standard (2001), where the quality of digital collections can be measured from the quality of the content, access collection and information retrieval. This study aims to analyze the quality of digital library collection of Airlangga University using quantitative discriptive method with 100 respondents. Based on the research result, it can be concluded that the quality of digital library collection of Airlangga University is very good, that is 87.32% with assessment for collection content (86.72%), access collection (93.33%) and information retrieval (81.93%). Development needs to be done to model information retrieval in order to use the weighting method and index because the method used only uses query methods without considering the user's searching behavior.
