Abstract:

This article provides an overview of computer based catalogue systems designed for use by library clients, seeing present day ‘discovery systems’ on the same trajectory as the older ‘online public access catalogues’ (OPACs) which they are gradually replacing, both in technical development and their approach to client use scenarios. It traces the history of the OPAC/discovery system from its origins in the library automation of the 1960s through to the present and discusses the main technical standards which have formed its development. The article goes on to consider questions relating to the usability of electronic library catalogues and highlights semiotic and ethical issues inherent to their design. It concludes with reflections on the future of the OPAC/discovery system in an information universe apparently dominated by the internet search engine.

Abstract:

The behavior of academic library users has drastically changed in recent years. Internet search engines have become the preferred tool over the library online public access catalog (OPAC) for finding information. Libraries are losing ground to online search engines. In this paper, two aspects of OPAC use are studied: (1) the current OPAC interface and searching capabilities, and (2) the OPAC bibliographic display. The purpose of the study is to find answers to the following questions: Why is the current OPAC ineffective? What can libraries and librarians do to deliver an OPAC that is as good as search engines to better serve our users? Revitalizing the library OPAC is one of the pressing issues that has to be accomplished.

Abstract:

This study aims to explore common pitfalls of design and functional issues of Open Public Access Catalogue (OPAC) systems for archives for the general public and suggest solutions to approach such problems. Other than general users, this study also suggests ways to enhance the OPAC system to make it more user-friendly to users with special needs, such as the elderly and children. This paper uses a case study approach to evaluate the usability of the OPAC system in the Hong Kong Film Archive (HKFA), which is a representative and important archive of its type. The paper provides practical insights on common pitfalls of design and functional issues of OPAC for archives under such context (such as searching user-friendliness) and suggests technical solutions (such as Web 2.0 and more user friendly input devices) to approach such problems. Although we carried out this usability study mainly based on observation without direct interaction with their target users, we already discover adequate and significant problems for the discussions and suggestions in this paper. The paper includes implications and suggestion for archives to improve the usability and functionality of their OPAC systems, which is a key to their public services. Recently, implementing public Web-based access to archives has become popular. However, there are just few usability studies on such OPAC systems, especially for archives facing the general public instead of just professionals.

Abstract:

Conventional traffic-control strategies have limitations in handling unanticipated traffic demands. An adaptive traffic-signal control is expected to mitigate this problem and improve overall system performance. Furthermore, with the increasing needs of evolving intelligent transportation systems, traffic signals are expected to provide significantly greater functionalities, which can be achieved only by adaptive control. A product of many years of development, Optimized Policies for Adaptive Control (OPAC) represents a significant step forward in adaptive signal-control research. The OPAC strategy was field-tested at a New Jersey site. The performance of OPAC was compared against a well-designed time-of-day signal control. The evaluation was performed under various traffic-demand conditions and included both isolated intersections and arterial sections. The analysis indicated a highly significant improvement with OPAC control. OPAC showed its best performance during oversaturated conditions. It reduced the travel time and number of stops by about 26 percent and 55 percent, respectively, for the entire arterial section. OPAC also improved traffic performance during changing demand conditions. It significantly improved the performance of an isolated intersection during undersaturated traffic conditions. OPAC reduced stopped delay on the major-street approach by 40 percent without affecting the minor-street performance.

Abstract:

The British Library launched in 1986 a Catalogue Action Plan to deal with the long-term prospect of declining financial and manpower resources, the absence of growth in the market for its services, an unacceptably large backlog of uncatalogued materials, and a steadily increasing annual output of British publications to be catalogued. The initial phase of the Plan was designed to contain staff costs by reduction and simplification in data content in BNBMARC and other British Library records, predicating their future use primarily in an online (OPAC) environment. It has had significant success for the British Library's aims in the first full year of implementation, but it has raised questions of the cost-benefit in centralized cataloguing services for the library community, in respect both of the costs and sizing of OPAC systems in local libraries and of the necessity of sustaining indefinitely the high cost of adherence to international standards established before OPACs, the CD-ROMs and OSI had changed the technology.

Abstract:

Purpose – The purpose of this paper is to determine whether features of next-generation Online Public Access Catalogue (OPAC) interfaces are useful and intuitive to users who have different levels of searching ability. In addition, it investigates whether there is a difference between librarians’ and students’ preferences for specific features. Design/methodology/approach – The research is based on 18 semi-structured interviews conducted in July 2012 with three groups of library users from The University of Sheffield: librarians; Master of Arts Librarianship students; and a group of other post-graduate students. Findings – Overall, this study suggests that while the next-generation catalogue interfaces and features are useful, they are not as “intuitive” as some previous studies have claimed. Interviewees appeared to prefer the searching and browsing options over the Web 2.0 features. Both librarians and students have similar opinions regarding the usefulness of next-generation OPAC features, but preferences are complex. Research limitations/implications – The study is based on one institution, and the disciplinary background of the post-graduate students was limited. Practical implications – Promoting next generation OPACs and explaining their features to users is essential. Originality/value – The paper adds to the understanding of users’ preferences in relation to next-generation OPACs, locating the findings of the current findings firmly in the context of previous literature.

Abstract:

Online Public Access Catalogue is playing a vital role in Central Libraries and University/College Libraries. Most of the College libraries are using OPAC for easy search and retrieval of the books and it's Status in a Particular Library. The main limitation in the OPAC we are using in current system is; that we are able to search and retrieve the information about the books of that particular library, but not outside of it. When we have a scenario like if we have multiple libraries in a campus, if we need to search a book in all the libraries, we have only two possibilities to build OPAC, once to make the single database for all the Libraries or you need to ask the user to search in all OPAC Systems of respective Library manually. But both above solutions are not feasible in real time environment. So in order to have the above scenario a feasible solution we need to build a distributed environment for the OPAC, which will have all the individual databases connected remotely.

Abstract:

A longitudinal study of three discrete online public access catalog (OPAC) design enhancements examined the possible effects such changes may have on circulation and resource sharing within the automated library consortium environment. Statistical comparisons were made of both circulation and interlibrary loan (ILL) figures from the year before enhancement to the year after implementation. Data from sixteen libraries covering a seven-year period were studied in order to determine the degree to which patrons may or may not utilize increasingly broader OPAC ILL options over time. Results indicated that while ILL totals increased significantly after each OPAC enhancement, such gains did not result in significant corresponding changes in total circulation.

Abstract:

This article proposes adding keywords and descriptors to the catalog records of electronic databases and media items to enhance their discovery. The authors contend that subject liaisons can add value to OPAC records and enhance discovery of electronic databases and media items by providing searchable keywords and resource descriptions. The authors provide an examination of OPAC records at their own library, which illustrates the disparity of useful keywords and descriptions within the notes field for media item records versus electronic database records. The authors outline methods for identifying useful keywords for indexing OPAC records of electronic databases. Also included is an analysis of the advantages of using Encore’s Community Tag and Community Review features to allow subject liaisons to work directly in the catalog instead of collaborating with cataloging staff

Abstract:

The purpose of the article is an analysis of evolutionary stages in the development of online-catalog and the requirements to these services in the context of customer orientation. The methodological basis of scientific intelligence is a customer-oriented approach that allows studying library products and services through the prism its accordance and level of satisfaction needs of customers (users) in the library; the principle of historicism, allowed to identify the origins of online cataloging, the stages of its development and quality of online-catalogs; source analysis and synthesis. The scientific novelty is the technological evolution of online catalogs were studied the first time in the Ukrainian library and the modern requirements to these services in the context of customer orientation and web 2.0 technologies are defined. Conclusions – automation of library at the current stage should be concentrated on developing and deploying electronic catalogs which are suited to the expectation of the new generation as competent web users. Improving the search tools should not be directed at the library staff but used for breaking down the barriers that users have when trying to navigate in different library resources and websites therefore will be possible while the architecture of modern automated library information systems does not interfere with the cooperation of the user and catalog. The evolutionary solution to this problem can be a reconstruction of automated libraries and information systems in the way by changing their architecture to one the user is orientated.

Abstract:

Online Public Access Catalog (OPAC) is one of the e-catalog information technologies applied in libraries. OPAC is a library information retrieval system that can be accessed online. State Islamic University of Sunan Kalijaga Yogyakarta has been using OPAC since 2012 and OPAC users are increasing from year to year. An information system will be used by users if it suits their needs. The successful implementation of OPAC raises questions about the factors that influence this success. For this reason, this study aims to determine the factors that influence users to use OPAC. Structural Equation Modeling (SEM) is a multivariate statistical technique which is a combination of factor analysis and regression analysis (correlation) which aims to examine the relationships between variables in a model. Processing using SEM will be carried out to find the relationship between the variables to be tested, which variables are interconnected, and are there any unrelated variables. The results of processing the variables using SEM can show what variables attract users to use the e-catalog. Acceptance of information systems can be measured by several evaluation models that have been developed at this time. There are many evaluation models used to measure. Technology Acceptance Model (TAM) is the appropriate model to use for this study, because this study is about the acceptance of a system. In addition, several previous studies used by researchers as references also used TAM as their study method to assess user acceptance of a system. This study modifies TAM, which is used to determine user acceptance of an information system, by adding three exogenous variables, information quality, perceived enjoyment, and user interface. Results of this study proved that information quality, user interface, perceived usefulness, perceived ease of use, and behavioral intention to use, are all factors that influence the actual use of OPAC. Perceived enjoyment is a variable that cannot be proved affects the actual use of OPAC.

Abstract:

Purpose The aim of this paper was to compare university students’ preferences for searching the library catalogue via the library’s Koha online public access catalogue (OPAC) or its discovery tool VuFind. Design/methodology/approach A total of 175 students responded to a questionnaire-based survey through which their demographic data, duration (years) of computer use and their self-reported levels of computer skills were obtained. Students were asked what interfaces they use for catalogue searching and to rate their opinion on the relevant interfaces on a seven-point Likert scale. Mann–Whitney and Kruskal–Wallis tests were conducted to statistically compare the differences between students’ demographic/individual characteristics and their ratings on the respective interfaces. For those students who used both systems, differences between their Likert ratings were assessed using a one-tailed Wilcoxon signed rank test. Findings The results showed that there were no significant differences among students in terms of their ratings on either the OPAC or VuFind interfaces. Wilcoxon signed ranks test indicated that significantly more students thought that VuFind was more usable than the Koha OPAC. Originality/value This is a pioneering study of the current use of the OPAC and discovery tools by university students and their preferences for searching catalogue information through these systems. It is hoped that the findings of this study will encourage researchers to conduct task-based usability studies with various cataloguing tools and this could yield new and improved interaction designs for library catalogue searching.

Abstract:

The study investigated undergraduate’s awareness, utilization and satisfaction with online public access catalogue (OPAC) in selected University libraries in Nasarawa State, Nigeria. Four (4) objectives with corresponding research questions guided the study. The study adopted survey research design. The population of the study was 7,233 registered library users (undergraduates) in two (2) public universities in Nasarawa State, namely Federal University Lafia (FULAFIA) and Nasarawa State University, Keffi (NSUK). The sample size for the study was 379 drawn using Taro-Yemene’s formula for sample size determination. Proportionate stratified random sampling technique was used to select the sample of respondents from the two (2) universities under study (i.e.) FULAFIA with 150 and NSUK, 299 respectively. Questionnaire was used as instrument for data collection. A total of 379 questionnaire were distributed and 362 retrieved for analysis representing a percentage of 95.5%. Data was analyzed using frequency counts; mean scores and standard deviation. Findings of the study revealed that, undergraduates were highly aware of Online Public Access Catalogue in selected University Libraries in Nasarawa State. The finding also revealed, undergraduates in selected university libraries in Nasarawa State utilized OPAC to a little extent and students were not satisfied with the use of OPAC, hence their extent of satisfaction derived from the use of OPAC was little extent. Findings further revealed factors affecting use of OPAC by undergraduates in selected university libraries to include: library guide to explain how to use the OPAC is not available, unstable power supply, library staff not friendly, network/server problems, lack of computer systems, among others. Finally, conclusion and recommendations were made based on the findings of the study.

Abstract:

In recent years there has been a growing international interest in alternative certification strategies for organic products. Specifically, participatory guarantee systems (PGS) have proved to be particularly suitable not only to simplify bureaucratic procedures for small organic producers and reduce the cost of certification, but also to generate empowerment, social inclusion and mutual support among farmers. The purpose of this paper is to study the elements of social capital (SC) found in a PGS through the use of social network indicators using the Organizaçao Participativa de Acreditaçao e Certificaçao “Orgânicos Sul de Minas” (OPAC-OSM) as a case study. The research was carried out in the southern part of Minas Gerais, one of the states of the Brazilian Federation, where organic production represents a viable alternative for small and medium-sized farmers. In particular, a survey was carried out to capture the opinions of managers (presidents or directors) about their participation in the OPAC-OSM, and about the level of interaction and degree of trust between members. Relational skills, which are the basis of structural SC, were analyzed both at the level of individual units and at the level of the general network of the OPAC-OSM. An in-degree centrality score assigned to OPAC-OSM members was obtained from each network. These scores have been correlated with variables of the database that were chosen due to their relevance in assessing the level of social capital. According to the results, the factors that most reinforced the proof of SC among the OPAC-OSM members were the level of information and the degree of trust and collaboration networks, with special emphasis on female participation. From the analysis carried out, it is possible to conclude that PGS are powerful tools in the strengthening of SC far beyond the aspect of quality assurance, which remains the main objective of the OPAC.

Abstract:

Disarpus Bandung is a technical institution that has the task and function of developing the habit of reading fondness through library empowerment. The role of the Online Public Access Catalog (OPAC) as an information retrieval system is very supportive as a means or facilities to improve services to the community, especially in the field of libraries in the city of Bandung. This study aims to determine (1) How is recall and precision in the OPAC of the Disarpus Bandung. (2) effectiveness of OPAC as an information retrieval system in the city of Bandung. The data collection method used is by conducting keyword searches on the OPAC of the Disarpus Bandung through the website page http://layanan.dispusip.bandung.go.id/inlislite3/opac/. These 10 keywords were the most searched or searched by library users in March 2022 in Disarpus Bandung. Every keyword used in the search process, the result is a number of catalog data. The catalog data obtained is then analyzed and determined which data are relevant and irrelevant to the information needs sought based on the title, the subject of the book, and the availability of the collection. Then the recall and precision calculations will be carried out to determine the effectiveness of the INLISLite application retrieval. Based on the results of testing on the OPAC of the Disarpus Bandung with 10 keywords most frequently searched by users during March 2022, it can be concluded that the information retrieval system has been effective. This can be seen from the average recall value of 0.96 or 95.79% and the average precision value of 0.92 or 92.31%. Of the 10 keywords, namely nursing, human resources, communication, research methods, accounting, taxation, information systems, skills, parenting, and psychology, the keywords with the highest recall and precision values are research methods and parenting keywords, namely the recall value of 1 or 100% and a precision value of 1 or 100%. Meanwhile, the lowest recall and precision values are communication keywords, with a recall value of 0.90 or 90.34% and a precision value of 0.88 or 88.33%. Overall, the OPAC at the Disarpus Bandung has been effective as an information retrieval system.

Abstract:

It is known that end users of products and services sometimes innovate, and that innovations developed by users sometimes become the basis for important newcommercial products and services. It has also been argued and to some extent shown that such innovations will be found concentrated in a “lead user” segment of the user community. However, neither the characteristics of innovating users nor the scope of the community that they “lead” has been explored in depth. In this paper, we explore the characteristics of innovation, innovators, and innovation sharing by library users of OPAC information search systems in Australia. This market has capable users, but it is nonetheless clearly a “follower” with respect to worldwide technological advance. Wefind that 26% of users in this local market nonetheless do modify their OPACs in both major and minor ways, and that OPAC manufacturers judge many of these user modifications to be of commercial interest. We find that we can distinguish modifying from nonmodifying users on the basis of a number of factors, including their “leading-edge status” and their in-house technical capabilities. We find that many innovating users freely share their innovations with others, and find that we can distinguish users that share information about their modifications from users that do not. We conclude by considering some implications of our findings for idea generation practices in marketing.

The purpose of this paper is to understand the characteristics of cross-device OPAC searches, and to identify query reformulation (QR) patterns during device transitions. Design/methodology/approach The transaction log from a university library, spanning six months, was used to conduct the quantitative analysis. The query vocabulary richness, which refers to the average number of unique words each query contains in a search session, can evaluate query diversity, and contribute to the analysis of QR. Findings The results show that PC-PC transition is the most important pattern of device transition. The time interval of device transition was different to the time interval of transitions in web searches. Short device transitions mainly occurred in daytime, and the number of transitions that occurred in less than one minute was higher than on the web. Searches for Industry and Technology triggered the most device transitions, and the users tended to choose the same search field. In addition, the authors made a detailed analysis of the reasons for same-type device transitions and different-type device transitions. Furthermore, the authors focused on the characteristics of adjacent QR patterns. The authors not only refined the concept of cross-device to include the same-type device transition, but also summarized the characteristics of the cross-device QR patterns, which can be used to predict post-switch queries. Originality/value This study extends research into cross-device interaction and cross-device search to the domain of digital library research. The authors also introduced QR perspective on cross-device interaction on OPAC.

Abstract:

Purpose The aim of this paper is to empirically examine the usability of the Koha OPAC from a user perspective. Design/methodology/approach A series of usability tests with Koha were carried out at a private university in Bangladesh. Both experienced and novice users participated in these tests. Experienced users participated only once, whereas novices took part in three successive sessions. At first, novices’ initial performance was recorded. Then, they performed the same tasks after a short training tutorial. Novices again participated in the retention experiment with the same tasks after four weeks. A set of seven tasks was given to the users to see their performance in terms of time taken, number of errors made and success scores. Performance data were captured through a computer screen recording software, and satisfaction scores were obtained using a modified version of Questionnaire on User Interface Satisfaction (QUIS). Comparisons of performance and satisfaction with Koha OPAC were made between experienced users and novices’ initial, learning and retention experiments and amongst novices’ three test sessions. Findings The results showed significant performance difference between experienced and novices’ initial session. Novices could easily pick up the functionality of Koha OPAC when a brief training was provided. The comparative analysis of performance between experienced users and novices’ learning showed no significant difference between these sessions. There was a significant difference between experienced and novices’ retention in terms of success scores. The comparison amongst novices’ initial, learning and retention sessions showed significant performance differences in time taken and errors made. The QUIS results also showed significant differences in subjective satisfaction for several items between experienced users and naïve sessions, and for one item amongst novices’ three experiments. Originality/value This is a pioneering study of the task-based usability of Koha OPAC. The findings from this study will encourage researchers to empirically examine the usability of other open-source ILSs, which might result in improved user performance and satisfaction with these systems.

Abstract:

The author continues with her study initially presented in the article “The possibilities of information search in electronic platforms of Russian libraries” (A. V. Kulikova. The possibilities of information search in electronic platforms of russian libraries // The Journal of Encyclopaedic Studies. – 2019. – No 2. – P. 30–52). She demonstrates the methods to be applied for business information search related to local encyclopaedic book publications and identifies the principles to find recent publications promptly and to satisfy user demands most effectively. The bibliographic search success depends upon how the user understands the system. Optimum query formulation saves time and excludes information noise. The key characteristics of library digital information retrieval systems are discussed. The computer systems of 113 regional libraries were analyzed within the study. The following automated library information were tested objectively: IRBIS, RUSLAN, OPAC-Global, Foliant, MacWeb. The author does not intend to advertise or subvertise any ALIS. Her main goal is to reveal the convenient and speedy retrieval methods with existing functionalities.

Abstract:

In 1969 a number of Dutch university libraries and the Royal Library decided to cooperate in the field of library automation by creating a consortium for a Project for Integrated Catalogue Automation (Pica). In 1978 an online shared cataloguing system came into operation. About five years later the Pica system began to be used to produce the Dutch National Bibliography and the Dutch Union Catalogue, and to process all the cataloguing activities for over 900 public libraries. The Pica Online Retrieval System (ORS) enables users to consult bibliographic databases and catalogue information from the central Pica database. These central systems, together with local systems such as the Online Public Access Catalogue (OPAC), the Acquisitions System combined with Serials Control, and the Circulation Control System, now constitute a ‘total library system’.

Abstract:

This article describes how as internet technology continues to change and improve lives and societies worldwide, effective global information management becomes increasingly critical, and effective Internet information retrieval systems become more and more significant in providing Internet users worldwide with accurate and complete information. Search engine evaluation is an important research field as search engines directly determine the quality of information users' Internet searches. Relevance-decrease pattern/model plays an important role in search engine result evaluation. This research studies effective measurement of search results through investigating relevance-decrease patterns of search results from two popular search engines: Google and Bing. The findings can be applied to relevance-evaluation of search results from other information retrieval systems such as OPAC, can help make search engine evaluations more accurate and sound, and can provide global information management personnel with valuable insights.
