    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
    Reports on a study at an elementary school in Washington, DC examining pupils' use of an OPAC. Presents this within the overall instructional environment of the school in order to open a window on the broader interaction of children, technology, curriculum, instruction and learning. Explains the methodology used in the study, the findings of the study, and notes a number of conclusions. Focuses in particular on the patterns of success and failure of children's use of the OPAC, their search strategies and the nature of their interaction with the OPAC

    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
    Research on the use of online catalogs has challenged many assumptions about the behavior of library users. It has demonstrated that many of the patterns of behavior observed in the use of card catalogs were adaptions to the card technology; often behavioral patterns are different in an online environment. These studies have indicated that patrons prefer online catalogs and use them more, but they also show inadequacies in bibliographic practice, especially in the area of subject access.

    Abstract
    Although technology can often correct spelling errors, the complex tasks of information searching and retrieval in an online public access catalog (OPAC) are made more difficult by these errors in users' input and bibliographic records. This study examines the search behaviors of 38 university students, divided into groups with either easy-to-spell or difficult-to-spell search terms, who were asked to find items in the OPAC with these search terms. Search behaviors and strategy use in the OPAC and on the World Wide Web (WWW) were examined. In general, students used familiar Web resources to check their spelling or discover more about the assigned topic. Students with difficult-to-spell search terms checked spelling more often, changed search strategies to look for the general topic and had fewer successful searches. Students unable to find the correct spelling of a search term were unable to complete their search. Students tended to search the OPAC as they would search a search engine, with few search terms or complex search strategies. The results of this study have implications for spell checking, user-focused OPAC design, and cataloging. Students' search behaviors are discussed by expanding Thatcher's (2006) Information-Seeking Process and Tactics for the WWW model to include OPACs.

    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
