- Abstract
- Purpose - The objective of this study is to establish the opinion of users with respect to the awareness and utilisation of, as well as their satisfaction level with, the use of the online public access catalogue (OPAC). Design/methodology/approach - The paper deals with the applicability and utility of OPACs in five libraries in New Delhi, namely the Indian Institute of Technology; Jawaharlal Nehru University Library; Dr Zakir Husain Library, Jamia Millia Islamia; National Information System for Communication and Information Resources (NISCAIR); and the Defence Science Information and Documentation Centre (DESIDOC). A questionnaire was developed and distributed randomly to 128 users including undergraduates and post graduate students as well as MPhil. and PhD scholars. Users returned 115 completed questionnaires of which 100 were selected for analysis. Findings - The paper finds that the OPAC system has changed the traditional concept of access to library resources. It allows simple as well as complex searches. Document access is still one of the most important approaches of users to visit the library, and a study of the effectiveness of an OPAC is useful in this respect. Regarding results, sometimes users face problems of recall and precision. However, in some searches users are not able to find relevant documents on account of various factors. Data show that a high percentage of respondents are utilising the OPAC as a search tool for retrieving documents. Also, most of the users handle the OPAC themselves. Significantly, the satisfaction level of users was high with the OPAC facilities. Nevertheless, not many users are aware of the expert searches provided by OPAC. Originality/value - The paper focuses on many aspects of OPACs, particularly those in India. Librarians, especially those from developing nations, may choose their library automation software packages keeping in view the user's expectation with respect to OPACs.

- Abstract
- LIAS, the Pennsylvania State University's (Penn State) integrated interactive online system, provides for messaging by the user to inform library staff of errors found in bibliographic records. The message is sent by use of the OOPS command, and results in a printout which is used by processing staff for online catalog maintenance. This article describes LIAS, the use of the OOPS command, the processing of the resulting OOPS reports, an assessment of the effect of its use, and some speculation on the expansion of the LIAS message system for use in catalog maintenance.

- Abstract
- The GUI is impacting library application software. Despite this trend, user satisfaction with the GUI has not been documented. The Parke-Davis Pharmaceutical Research Library, USA, undertook a study to determine user satisfaction with the new GUI based Dynix Marquis, as compared with the Dynix Classic OPAC. The study included a survey assessing user satisfaction and a review of overall usage. Survey findings show that the GUI based OPAC was preferred by end users over the text based OPAC. Usage reports supported the survey findings with significantly increased usage after migration

- Abstract
- Historically, library automation has focused attention on the automation of internal library processes, such as cataloging; however, a new generation of library automation systems intended for direct use by library patrons is emerging. These public-access computer systems are categorized and described. The types of public-access computer systems are: (1) catalog information systems, (2) electronic information systems, (3) information presentation systems, (4) instructional systems, (5) consultation systems, (6) information service and delivery systems, (7) conferencing systems, (8) integrative systems, and (9) end-user computing facilities. To be effective, these computer-based systems must be integrated with the traditional collections and services of libraries

- Abstract
- Reports on the design of a GUI for the Okapi 'best match' retrieval system developed at the Centre for Interactive Systems Research, City University, UK, for online library catalogues. The X-Windows interface includes an interactive query expansion (IQE) facilty which involves the user in the selection of query terms to reformulate a search. Presents the design rationale, based on a game board metaphor, and describes the features of each of the stages of the search interaction. Reports on the early operational field trial and discusses relevant evaluation issues and objectives

- Abstract
- Analyses the OPAC at the Australian Catholic University in New South Wales, Castle Hill Campus using an object oriented model following Rumbaugh's methodology, as described in 'Object oriented modelling and design, 1991'. The process of analysis, although difficult, is one of the most effective ways of determining each function of a system of this kind. The methodology is especially useful as the data structure, behavioural and functional aspects of the system are displayed in separate diagrams. This is an advantage for those analysing systems, who can display many factors without confusing different aspects involved in the analysis process

- Abstract
- By the mid 1980s online bibliographic systems retrieved excessively large sets. Conversely, with standard Boolean systems, searches retrieved commonly nothing or too few records. In Nov. 92, 32% of searches yielded nothing from a retrieval set averaging 98. Offers solutions to these problems using MELVYL as a case study. Examines how non topical data such as date, language and location of document can improve topical searches. Explains OASIS and front end phototyping. Discusses adaptive retrieval, strategic commands, expanded retrieval and developments of OASIS. Covers aggregation of filtered sets, related terms, automatic progressive truncation, the SUMMARIZE LIBRARIES command, filing and filtering and collection analysis

- Abstract
- Several studies on OPACs have been made since the early 1980s. However, OPAC development has been governed by systems designers, bibliographic networks and technical services librarians, but not necessarily according to user needs. Existing OPACs demonstrate differences, for example, in the range and complexity of their functional features, terminology and help facilities. While many libraries have already established their own OPACs, there is a need to bring together in the form of guidelines or recommendations a corpus of good practice to assist libraries to design or re-design their OPACs.
As mentioned above, the guidelines are intended to apply to all types of catalogue, including Web-based catalogues, GUI-based interfaces, and Z39.50-web interfaces. The focus of the guidelines is on the display of cataloguing information (as opposed to circulation, serials check-in, fund accounting, acquisitions, or bindery information). However, some general statements are made concerning the value of displaying to users information that is drawn from these other types of records. The guidelines do not attempt to cover HELP screens, searching methods, or command names and functions. Thus, the guidelines do not directly address the difference between menu-mode access (so common now in GUI and Web interfaces) vs. command-mode access (often completely unavailable in GUI and Web interfaces). However, note that in menu-mode access, the user often has to go through many more screens to attain results than in command-mode access, and each of these screens constitutes a display. The intent is to recommend a standard set of display defaults, defined as features that should be provided for users who have not selected other options, including users who want to begin searching right away without much instruction. It is not the intent to restrict the creativity of system designers who want to build in further options to offer to advanced users (beyond the defaults), advanced users being those people who are willing to put some time into learning how to use the system in more sophisticated and complex ways. The Task Force is aware of the fact that many existing systems are not capable of following all of the recommendations in this document. We hope that existing systems will attempt to work toward the implementation of the guidelines as they develop new versions of their software in the future.

- Abstract
- Stanford University's Socrates II and University of California at Berkeley's Pathfinder are 2 USA World Wide Web based online publication access catalogues under development. They differ in their design language (how an interface functionally and visually communicates to the users). Evaluates each system's interface design and their ability to communicate functionality to users: analyzes design in terms of: colour, buttons, metaphors, layout, and basic and advanced search modes. Concludes that the design languages of both systems have the right directive and have the potential to evolve

- Abstract
- Paper presented at the Database Users' Conference in Toronto, 8.11.90. Discusses the reasons why it is the worst of times for most vendors developing software. Lists searching problems experienced by end users and discusses the difficulty of obtaining information by vendors from informed users in a timely manner. Presents a summary of screen design guidelines suggested as a result of 3 invitational conferences, held between 1984-86 to discusses results of research on screen design, and which caused some vendors to improve their system

- Abstract
- The Medical Film and Video Library (MFVL) of the Wellcome Trust in London, UK, has recently developed an online catalogue of nearly all the audiovisual holdings of the Wellcome Trust. Describes how this small audiovisual collection has managed to develop an automated online catalogue using existing software and in-house expertise focusing on: principal considerations in choosing library software; development of the database; addition of the MFVL database to the WISDOM service, and piloting

- Abstract
- Graphical queries involving 14 different query concepts were used in a study with 27 subjects. The results show that well designed graphical queries can be comprehended without teaching. Not so well designed queries are difficult to comprehend. The natural ability to specify graphical queries is not as good. The results identify clearly those concepts that are naturally easy to specify, and those that are difficult. The findings can be used for designing graphical interfaces, as well as for designing training packages
