- Abstract
- Paper presented at the 1992 IATUL seminar in Tallinn, estonia: 'Universal Availability of Publications in Science and Technology including those on the history and philosophy of grey literature' on UAP policy and practice. Discusses surveys conducted at the Helsinki Univ. of Technology Library analysing the use of the online catalogue. Covers the Internordic Study 'Monitoring the Online Catalogues of the Nordic Technical University Libraries', whose aim was the promotion of end-user accessibility to information as part of a training program. Users' search behaviour was observed during the course on the library's TENTTU information retrieval system. Analyses the transaction log files of end users. Presents statistics on the distribution of search elements in free text and field codes and the use of Boolean operators. Comments on a software package enabling analysis of the interaction between the system and the end user. This may be useful to evaluate training programs

- Abstract
- Describes the design and continuing development of the University of Illinois at Urbana-Champaign Library Information Workstation, which provides the primary, in-library user acces to ILLINET Online Plus, the library's extended OPAC system. Briefly describes the automated library information resources and information processing environment as they have influenced the design and development of the Library Information Workstation. Discusses its philosophy and approach in the context of relevant information access issues and user needs and requirements. Features of the current Library Information Workstation implementation are then described using illustrations focused particularly on integrated access to local (resident on individual workstations) information fields and an integrated end user interface for bibliographic database searching. Ongoing development plans also are discussed briefly

- Abstract
- One of the most common errors in cataloguing library materials involves miscoding of the nonfiling indicator of title fields. Notes the extent of the problem and its negative effect on searching in the library's online catalogue and surveys how librarians have approached solutions to the problems. Describes how the major library automation system address this problem

- Abstract
- In one form or another, from a mental list in the mind of the librarian, to book catalogs, card indexes, and online information retrieval systems, some type of meta access has existed to guide library users through library collections. Over the last 40 years, these constructs of paper and wood evolved into Online Public Access Catalogs (OPACs). When the catalog shifted out of drawers and off of three by five cards to become a networked, universally accessible entity, its role in the library shifted as well. The OPAC competes with the World Wide Web, metadata registries, search engines, and more sophisticated database structures for attention. Amongst this assortment of access mechanisms, the purpose of the OPAC has become muddled. The OPAC has now become one information source among many and one of a number of portals for accessing library collections and beyond.

- Abstract
- The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.

- 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
- Library OPACs have long been the gateways between users and information. They present to users the achievements of library automation, and are the most widely available automated retrieval systems and the first that many user encounter. Current trends in OPAC design are toward a user oriented, individual information service which can meet the different needs of users with a variety of background and interests. Compared with the rather inactive, short term and general information service of conventional systems, this type of system focuses on active, long term and personalized service. Proposes a framework for the design of such an OPAC and discusses some recent developments in personalized information service

- Abstract
- This article first compares and contrasts the essential, fundamental differences between traditional and digital information mediums. It then reexamines the role of the online public access catalog (OPAC), refines the definition of library's catalog, and advocates the addition of Internet resources within the OPAC. Next, the article describes the building of the Alex Catalog, a catalog of Internet resources in the in the form of MARC records. Finally, this article outlines a process of integrating the futher inclusion of other Internet resources into OPACs as well as some of the obstacles such a process manifests.

- Abstract
- The library of the Cité des Sciences et de l'industrie attracts 4.000 visitors daily of whom 25% consult the GEAC system OPAC. Describes a 1992 survey consisting of online questions followed by an interview. The questionnaires were adapted from ones used in the UK and utilised OLIVE (Online Interactive Validation and Evaluation). While difficulties arose from users' inconsistency in their replies and failures to answer questions, it has become clear that subject access is unsatisfactory, sometimes because of mistyping by the searcher but also because of the vocabulary problems and lack of guidance in search strategies

- 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
- As part of a recent research project a large set of catalogue users' subject queries was collected by interview. The libraries and the data collection procedures are briefly described. The query set obtained has been divided into several general categories which illustrate the range of of types of subject search being performed. Each category of query is discussed, with a consideration of the problem which face the user in carrying out each type of search. Possible solutions to some of these problems are considered. The most important issue is the variation in specifity of the queries, whilst other issues relate to the users' expression of need, access to specific types of materials, interdisciplinary subjects, and inappropriate queries. These issues are summarised and the implications for OPAC design are discussed

- 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.
