    Abstract
    The focus of this study is the search behavior of remote users of the University of California MELVYL Library System, an OPAC. Transaction logs from randomly selected remote user search sessions are analyzed. Descriptive data on the number and type of searches, choice of search mode and database, number of retrievals, number and type of errors, and use of system HELP facilities are presented. The search data have been cross-tabulated with demographic data on the same group of remote users, collected through an online survey conducted by the authors. Effectiveness of system usage is discussed. A case mode is made for the desirability of additional heuristics in the catalog portion of the system

    Abstract
    This article reprots the findings of an experiment employing a simulated scholarly use of an OPAC to determine the frequency of one-screen displays when a scholar searches for a known-item with so-called 'keywords' in an implied boolean system. The experiment revealed that a 'keyword' search formula comprising surname plus first and last title words produced a single screen 92.8% of the time, thereby reducing the failure of traditional title searching to produce single screens by nearly one half; such a formula also enables a scholar to search successfully with abbreviated, unsearchable bibliographic citations. Additional research should be carried out, for if it is further demonstrated that replacing traditional bibliographic catalog entries with transcribed title pages provides an improved known-item OPAC, users would benefit and libraries would enjoy huge savings

    Abstract
    The project explored the ways in which the online catalogue contributes, or does not contribute to the success of library users. Key issues examined included: whether students are really getting appropriate assistance when using the online catalogue; the most common searching successes and failures observed for people using the online catalogue without staff assistance; and the effectiveness of online catalogue use by librarians providing reference assistance compared to other sources (reference books, electronic and printed indexes). Reviews relevant studies of online catalogues and reference success and describes the methodology and results of 3 different online catalogue studies: the Reference Assessment Survey; the online catalogue study of unassisted users; and the document availability study; all conducted at San José State University Library; California, using the Reference Transaction Assessment Instrument. Considers the implications of the results for reference practice and study methodology

    Abstract
    Reports results of a questionnaire survey of lecturers and students, at Florida University at Gainesville, to determine the degree to which the information provided in catalogue records serve the needs of library users and the usefulness of including and displaying typical elements of catalogue records. Results indicate the highest level of agreement with usefulness of: title; primary author; date; subjects; other authors; and series. There were moderately high levels of agreement for: summary notes; contents notes; standard numbers; publisher; pagination; and related titles; and lower levels of agreement for reference notes; place of publication; index notes; illustrations; and size

    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
    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
    Many information channels are available to students, but it is now clear how students select and use them. Reports results of a study of the information seeking behaviour of students at 2 US universities: the American University; and the District of Columbia University. The study aimed to investigate: the information channels used by students when they work on course related projects and how they select the channels; how they use ALADIN, an augmented OPAC that provides access to the holdings of the Washington Research Library Consortium and several commercial online databases; and how selected characteristics of students are related to their use of information channels. Students identified convenience and quality of data as the top 2 factors in their choice of information channel. Affirms the value of librarians and of formal information channels, suggests ways to augment the online catalogue, and reminds librarians that equal access to information technology does not necessarily lead to equal use

    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
