- Abstract
- A survey of catalogue use in 1993 at Utrecht University in the Netherlands showed considerable dissatisfaction with the online catalogue's subject search facilities. Of those who used subject searching 64% preferred subject headings against only 2% who chose classification schedules. Library users make little use of the existing facilities for assistance and leaflets which are available in the library. It has, therefore, been decided to provide a programme of instruction in library use and to move towards a unified system of subject access to the library's catalogue

- Abstract
- Current online catalogs have problems providing reasonable subject access, often resulting in searches with too few or too many hits. These problems can be improved by enhancing MARC records, building semantic networks through cross-references, and linking subject headings to classification numbers. This paper describes a pilot project to design a hypertext search engine using these principles

- Abstract
- Presents a pilot study for an Internordic project to monitor the use of online catalogues in the Nordic technological university libraries. Focuses on the use of classification in subject searching, how the UDC is used and the extent of its use. Studies user interaction with the OPACs and improvements to information retrieval in the catalogues using the transaction log method to gather data. The pilot study examnines the TENTTU Books database which is the online union catalogue of the Helsinki Univ. of Technology Library, a multilingual database with true information retrieval. The Internordic study itself will make comparisons between the TENTTU system and the new Virginia Tech Library System. Discusses the users monitored, method of analysis, subject searching in the database, results and how the UDC codes were used. Compares this to other studies conducted in Finland and evaluates the project

- 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
- n this article, we report on the first large-scale study of end-user understanding of subject headings. Our objectives were to determine the extent to which children and adults understood subdivided subject headings and to suggest improvements for improving understanding of subject headings. The 1991 Library of Congress Subject Subdivisions Conference suggested standardizing the order of subject subdivisions for the purpose of simplifying subject cataloging, which served as the impetus for the study. We demonstrated that adults understood subject headings better than children; however, both adults and children assigned correct meanings to less than half of the subject headings they examined. Neither subject heading context nor subdivision order had an effect on understanding. Based on our findings, we challenge the library community to make major changes to the Library of Congress Subject Headings system that have the potential to increase end-user understanding of subject headings.

- Discusses the problems encountered by elementary school children in retrieving information from catalogues, either traditional card catalogues or OPACs. Describes an alternative system of classification using colours and symbols that was developed in The Common School of Amherst, Mass. The case study found that children do have the ability to use a classification scheme that is keyed to their developmental level and that employs both colours and symbols to facilitate their search efforts

- Abstract
- Research on the use and users of online catalogs conducted in the early 1980s found that subject searches were the most common form of online catalog search. At the same time, many of the problems experienced by online catalog users have been traced to difficulties with the subject access mechanisms of the online catalog. Numerous proposals have been made for methods intended to improve subject access to online catalog records. These commonly involve enhancing the catalog's bibliographic records with additional terms, or incorporating subject authority files or additional thesauri in the database. Another stream of research has concentrated on applying retrieval techniques derived from information retrieval (IR) research to replace the Boolean search methods of conventional online catalog systems. This study describes the results of retrieval tests using a variety of these search methods in the CHESHIRE experimental online catalog system.

- Abstract
- Reports results of a study to elicit information from the users of the Wisconsin University at Madison online catalogue (Network Library System (NLS)). The General Library System (GLS) conducted focus group interviews with undergraduate students, graduate students, and faculty. Undergraduate students tend to utilize subject searching capabilities. Graduate students and faculty utilize subject searching only as a last resort; they typically search by known author or title. A significant number of the participants reported experience with library online catalogues other than NLS, although the majority of faculty reported very little experience with other online catalogues. All the focus group participants, but particularly the undergraduate students, evidenced confusion between keyword searching and searching controlled vocabulary. Inclusion of circulation status in the bibliographic records was identified as an important feature of the catalogue

- Abstract
- As part of her doctoral dissertation at Brabant Catholic University in the Netherlands A. Oomens recently held a survey to determine the relative merits of author and subject arrangements for non fiction collections. Although users browsing through the collections were more likely to find material of interest via a subject arrangement, those looking for a particular title were best served by an author arrangement. All users interviewed preferred the arrangement with which they were familiar

- Abstract
- The second half of a 'before and after' study to evaluate the impact of an online catalogue on subject searching behaviour is reported. A holistic approach is adopted encompassing both catalogue use and browsing at the shelves for catalogue users and non-users. Verbal and non-verbal data were elicited from searchers using a combined methodology including talk-aloud technique, observation and a screen logging facility. An extensive qualitative analysis was carried out correlating expressed topics, search formulation strategies and documents retrieved at the shelves. The online catalogue environment does not appear to have increased the extent of subject searching nor the use of the bibliographic tool. The manual PRECIS index supported a contextual approach for broad and more interactive search formulations whereas the OPAC encouraged a matching approach and narrow formulations with fewer but user generated formulations. The success rate of the online catalogue was slightly better than that of the manual tools but fewer items were retrieved at the shelves. Non-users of the bibliographic tools seemed to be just as successful. To improve retrieval effectiveness it is suggested that online catalogues should cater for both matching and contextual approaches to searching. Recent research indicates that a more interactive process could be promoted by providing query expansion through a combination of searching aids for matching, for search formulation assistance and for structured contextual retrieval

- Abstract
- Investigates what effect the shelf classification of fiction had on the way that library users in the 2 branch libraries of Kajanni, Finland, use the library's stock of fiction and how they loan fiction. In 1 library the fiction stock was divided in 11 shelf categories, based on genres of fiction - in the other no changes were made. The books were also indexed and classified in the library's database. The project lasted for 3 years and the results were gathered by interviewing clients and making statistical analysis on loans in both libraries

- Abstract
- Reports a comparative study of OPAC use designed to investigate whether there are fewer zero or no direct hits due to users' misconceptions today than 10 years ago. Data from PEGASUS, Columbia University Law Library's INNOPAC based OPAC on failed searches was compared with that from an earlier study (see Cataloging and classification quarterly 4(1984) no.3, S.1-17) of LUIS, Northwestern University's NOTIS based OPAC. No direct hits resulting from a misconception of the system were found to constitute only half of the no direct hits compared with the corresponding category of the earlier study

- Abstract
- Uses an information processing approach to analyse the behaviour of end users in searching online bibliographic databases, with particular emphasis on errors made. Following instruction in online searching, 41 students and 3 faculty end users conducted 79 subject searches. Analysis of search transcripts identified 119 reasons for errors. Errors occured most frequently in connection with functions, moves, and elements of 'create and develop sets' and 'display and print records'. Surprisingly, the results do not indicate that end users make errors less frequently as they gain more experience and practice, although syntax-related errors do decrease with time

- Abstract
- Reports an empirical study at the Queriniana Civic Library, Brescia, of interaction betwee researchers and printed catalogues during bibliographic data retrieval. The study sought to ascertain frequency of catalogue use; research success rate and time taken; and to identify user profiles. Data were obtained by a mixture of questionnaires, interviews and direct observation. Findings showed that 64% of the catalogue users were female; 70% were aged 19-30; 65% were university students or had good school grades; and hardly any were working class. University students preferred keyword access. 50% or all searches were successful. Most search failures related to subject catalogues, which usually required more time. Provides statistics on time spent in research

- Abstract
- Describes a project which monitored electronically 11 public access terminals, at the Colorado University Librarys, to produce transaction logs that were used to gather statistics and analyze the behaviour of users when searching the library online catalogues. The study recorded user behaviour unobtrusively and focused exclusively on what actually occured during the search process. Among other findings it was revealed that the use of system supplied search aids varied, from low use of quick search and express search features, to more extensive use of search history and searching databases other than the home catalogue. Analysis of search results revealed that 66% of subject (keyword) and name searches produce 10 or fewer results, and 82% produce 25 or fewer titles, a manageable number for searchers to scan postings and spot relevant materials. User persistence in scanning titles was found to be high with the full list being requested for nearly 40% of searches netting up to 100 results. Overall, results show that emphasis on improved system design must be stressed if the needs of the majority of searchers are to be met more effectively

- Abstract
- Reports results of a study to investigate judgements made by searchers of online catalogues by using transaction log analysis to associate online catalogue searchmethods with decisions so as to retrieve location information. The study used the Mainframe Interface to Libraries Online (MILO), an interface to the Illinois Library Computer Systems Office (ILCSO) online union catalogue for the 45 academic libraries belonging to ILCSO. MILO provides access to a bibliographic database and directly links to another database with circulation and location records. As the latter database only provides location and circulation status, searchers' decisions to make links to such data are seen as an indication that the records being linked represent potentially useful material. Via a transaction log analysis, the linked location records were associated wiht the access points used to retrieve them in order to analyze the value and problems of searchers' uses of specific access points. Transaction logs were analyzed for a 38-day sample of the 1994 logs. Counting of records retrieved through the use of multiple access points (making the total greater than 100%), subject fields were used to access over 30%, author fields to access over 19%, and title fields to access over 51% of all records linked to location information. Other fields were used to retrieve very small percentages of linked records
