    Abstract
    This experiment explores the effectiveness of retrieving the listing of a known-item book from the 3.6 million entry onine catalog at the library of the University of Michigan using various combinations of author's name plus first and last title words. The principal finding was that 98.9% of the time a 1 to 20 line miniature catalog (minicat) was displayed that contained either the entry sought or a not-in-database (NID) reply when the search comprised all three words.

    Abstract
    Jansen and Pooch review three major search engine studies and compare them to three traditional search system studies and three OPAC search studies, to determine if user search characteristics differ. The web search engine studies indicate that most searchers use two, two search term queries per session, no boolean operators, and look only at the top ten items returned, while reporting the location of relevant information. In traditional search systems we find seven to 16 queries of six to nine terms, while about ten documents per session were viewed. The OPAC studies indicated two to five queries per session of two or less terms, with Boolean search about 1% and less than 50 documents viewed.

    Abstract
    FirstSearch is an on-line reference product from OCLC, launched in Oct. 91, that offers inexperienced end users searches easy access to on-line data bases through a simple menu interface. The flagship data base on the OCLC FirstSearch system is the Online Union Catalogue (Called WorldCat on FirstSearch). 14 data bases are available at time of press with a further 18 planned by the end of 1992. Although pricing of OCLC'a EPIC service is based on the standard connect time and display charges, the need for more predictable methods of charging led to FirstSearch use being sold in blocks of 500 searches. Bulk buying of blocks reduces the price per search from 90 cents (for 1 block) to 45 cents (from 160 blocks and above). Describes the experiences of Allen County Public Library, Indiana, one of the only 2 public libraries among the 16 initial test sites for FirstSearch

    Abstract
    Reports from a study investigating the extent to which academic end users conduct multiple search sessions, over time woth OPAC or CD-ROM databases at different stages of their information seeking related to a current research project. Interviews were conducted using a questionnaire with 200 academic end users at Rutgers University Alexander Library, NJ and University of North Texas, to investigate the occurrence of multiple search sessions. Results show that at the time of the survey interview, 57% of end users had conducted multiple search sessions during their research project and 86% of end users conducted their 1st search session at the beginning stage of their information seeking process. 49% of end users had conducted between 1 and 6 search sessions and 8% more than 6 search sessions. 70% of multiple search sessionss end users had modified their search terms since their 1st search session. Discusses the implications of the findings for end user training, information retrieval systems design and further research

    Abstract
    Describes the technical aspects of a feasibility study to test a new concept in bibliographic control based on the manifestations of a work. Conventional catalogues are based on the main entry principle which follows from the concept that there should be 1 main entry for each work. The Bradford OPAC project, at Bradford University, UK, aimed to develop a new type of hierarchical bibliographic record structure to cope with the problem of applying the main entry principle to multiple cataloguing records which are manisfestations of the same work. The project involved the storage of MARC data sets of bibliographic records, taken from the Bradford University Library OPAC and the OCLC WorldCat database, in a relational database (MS Access) on a PC. This was then used for an experimental Windows based OPAC, to evaluate the overall success of the idea and any problem areas identified with a view to a more substantial study. The project also aimed to test whether intelligent and responsive software, using a graphic user interface and based on sets of manifestations, could provide a better route to information than a display based on a single work

    Abstract
    This article reports on a qualitative study exploring: (1) strategies and behaviors of public library users during interaction with an OPAC; and (2) users' confidence in finding needed information on-line. Questionnaires, interviews, and observations were employed to gather data from 32 public library users. the results found search behaviors, confidence, and other feelings varied, based on 3 types of searches: unknown-item searches; area searches; and known-item searches. Term generation was the most important factor in unknown-item search strategies. Speed and convenience palyed a role in area searches, and simplicity characterized known-item searches. Of the 3 types, unknown-item searchers experienced the most frustration and doubt; known-item searchers the most disappointment; and area searchers the most confidence and contentment. Knowledge of these differences may prove helpful for librarians and interface designers
