Abstract

NORDINFO financed project to evaluate OPACs from the end user's viewpoint began in Aug 91 and was aimed at discovering how different types of users carry out searches; how the different methods of describing a publication's contact are used; and evaluating how title, thesauri words and free text are combined in searching using the transaction log analysis method over a 6 week period. The results show that not even menus give enough guidance to an occasional user; free text searching was the most popular method; scan commands proved not popular. The number of searches retrieving no-references was similar in all libraries, while libraries differed in the truncated search terms. Multilingualism was a serious problem in all the online catalogues. Lists recommended improvements

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

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

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
