- Abstract
- Three different interfaces for online public access catalogues were evaluated using transaction logging as a methodology. In two cases exercises were set and run against each interface so that results could be critically evaluated to indicate areas of weakness. In all cases a random transaction log was derived and this was used to diagnose system problems and identify patterns of behaviour. Results showed that searches were often difficult to categorise, users employing different approaches to the same end. Users also were prepared to undertake sustained searching until something was retrieved; however they then frequently stopped. Search input problems are also identified and possible areas for further research suggested

- Abstract
- For decades print pathfinders have complemented card catalogues and been useful reference tools. They are overlooked as components of online catalogues, even though they can extend the depth of the catalogue. To encourage librarians to consider integrating pathfinders into online catalogues discusses problems in OPAC searching, describes the value and styles of pathfinders, and illustrates how to include them in a NOTIS system

- 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
- 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
- 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
- Describes the availability, use and value of Z39.50, an international standard which allows a librarian accessing a database on one computer platform to search an OPAC hosted on another computer with a totally different database structure. Experiences of those working with the standard are given, and its use by the European Union IRIS project to link 6 major Irish research libraries is examined. Despite some problems encountered with different forms of author cataloguing and possible competition from the WWW, the standard is seen as possessing considerable strengths, for example in searching different catalogues and presenting the results in a standard format on screen, which justify the continuing interest of librarians

- Abstract
- The Bradford OPAC is an experimental prototype OPAC, with a graphical user interface, based on the manifestation concept. It was designed to study some of the problems in catalogues where there are many versions of the same work or complex multipart works. In place of the main entry based approach of one complete record for each item, the OPAC groups together into sets items that are manifestations of the same work. Users are presented with shorter lists of different intellectual works. Items in a set can be sorted, searched and displayed according to user supplied criteria

- Abstract
- A computerised presentation teaching method of NOTIS commands and search strategies in on-line catalogues was produced using ShowPartner F/X software. Students viewed the presentation and completed a NOTIS search exercise. A 2nd group of students from the same class completed the exercise without having viewed the presentation. A comparison of the 2 groups' exercises and transaction logs show that the group that viewed the presentation proved better at using correct NOTIS commands and formulationg effective search strategies. The greatest differences between the 2 groups were in subject searching (LCSH and keyword) and in locating specific items

- Abstract
- Desicusses the user training programme of the Helsinki University of Technology Library in the light of an internordic monitoring project. In the project, the use of OPACs was evaluated by analyzing the transaction logs and it was concluded that end users do not exploit the various possibilities of OPACs. A large part of the material found in the collections in the library is not retrieved: misspellings, lack of truncation, inequate use of Boolean operators and wrong database choices lead to ineffective retrieval. Emphasis in the online catalogue training has been on the 'hands on' exercises and it appears that the training programme is not very effective in the area of subject searching. Presents reasons for this and discusses plans for the future development of the library user training programme

- Abstract
- Describes the problems caused by the growth of bibliographic databases. Major problems are caused by seacrh systems based on Boolean operations because of the slowness, broad indexing and user difficulties due to present user links and search systems. Some suggested solutions are: use of combined search algorithms, more specific indexing, thesauri and improved user links

- Abstract
- EasyWeb is an Italian amde research program for library/archive users that allows simple access to Internet catalogue data via the WWW. The software is based on CDS/ISOIS and is currently available on the UNIX operating system with Intel 486 and Pentium processors. EasyWeb has been tested on the following operating systems: Olivetti, Sco, Novell UnixWare, Linux 1.2.13, Slackware with iBCS2; and in the new 1996 version will be installed on all other UNIX platforms (Solaris, HP, etc.). Names Italian academic bodies with EasyWeb installations and provides an Internet address

- Abstract
- Reports results of a study to determine the nature and extent of the problems discovered when cataloguing records for a consortium of 5 libraries were merged to create an OPAC. Records in the shelf list of the host library (Rhode Island University) were compeared to records in both the OCLC database and the OPAC. Problems were found to be most acute in sheared records, most commonly among those for reference materials and periodicals where host library holdings were often missing. Even for records present, call numbers were often missing, multi volume records were often incomplete, and records for theses and dissertations were confusing and misleading. A dirty database requiring some cleaning up of past cataloguing errors had been expected but the magnitude of the problem and the apparent overlaying of the first loaded records by subsequently loaded records was totally unexpected by cataloguing staff, thereby calling into question the process by which the shared database had been created

- Abstract
- Reports results of a questionnaire survey of UK academic libraries to determine the level of use of online public access catalogues (OPACs) and the development of inhouse subject indexes. 75 respondents reported having commercial systems and 7 reported inhouse systems. Data includes: named systems in use and numbers of libraries using each system; percentages of bibliographic records in machine readable format; types of materials; and record formats (UKMARC, LCMARC etc.) Reports the most common access points for searching the OPACs (author, keyword), methods of generating terms to be used for subject searching, subject heading sources (LCSH, MeSH, PRECIS) and classification schemes (Dewey (DDC), UDC). Results show that all universities and polytechnics now have OPACs and only the smaller colleges do not. OPACs are moving towards comprehensive covergae of academic library stocks with the MARC record the most popular format. The 3 main subject access strategies involve: LCSH, inhouse strategies, and strategies not based on controlled terminolgy. Draws heavily on the results of an earlier survey by Fran Slack (Vine 72(1988) Nov., S.8.12)
