Since the Online Computer Library Center (OCLC) unveiled its WorldCat Local library catalog discovery layer in 2008, library instructors have debated how to incorporate this tool into their teaching. WorldCat Local's faceted searching brings both educational benefits and unexpected challenges to the classroom. Instructors frequently hold formal…

This study examines what the public search for in the catalogue of the State Library of Victoria (SLV). As well as indicating the type of content being accessed, this gives an indication of what catalogue users expect of the State Library collection. A content analysis was undertaken of a random, stratified sample of 4,000 search queries typed in…

In this article, the authors compared the MLA International Bibliography database (MLAIB) across five vendor platforms to determine how and why seemingly comparable searches produced varying results. A number of tests were conducted using a variety of fields, terms, and parameters, and examples of results are provided. The authors' findings are…

Discusses the difference in subject access in OPACs (online public access catalogs) between subject searching (authority, alphabetic, or controlled vocabulary) versus keyword searching (uncontrolled, free text, natural language vocabulary). Compares a query on the term "garbage" in two online catalogs and discusses results. (Author/LRW)

Describes a longitudinal study of four sets of OPAC (online public access catalog) transaction logs that examined the effects of screen changes in helping searchers improve their search behavior. Results show that while screen changes initially had a positive impact on search behavior, they were not always sustained over time. (Author/LRW)

Discusses library use studies that examined library catalog search failures and demonstrates types of online catalog access that can reduce the failures caused by card catalog flaws or by user search errors by half. The use of single keyword, implied Boolean, or derived truncated key retrieval is suggested. (14 references) (LRW)

Describes an experiment conducted at the University of Illinois at Chicago that was designed to determine whether adding a substantial number of subject headings would raise circulation rates. The effects of added contents notes, keyword searching, browsing, and displays on the online catalog are examined, and further research is suggested. (27…

Describes a study that electronically monitored 11 public access terminals at the University of Colorado libraries to produce transaction logs that were used to gather statistics and analyze users' behavior when searching online catalogs. Implications for search instruction and systems design are suggested. (Contains 13 references.) (LRW)

This review of the research on the use of card catalogs and online catalogs highlights research methodologies and significant findings. Discussion of the results focuses on user needs and satisfaction, and the need to separate bibliographic practices that are universally sound from those that are an adaptation to the medium. (CLB)

Discusses the need to reevaluate bibliographic instruction in academic libraries for an expanded online environment based on experiences at Moorhead State University (Minnesota). Topics addressed include the addition of databases to local online catalogs; student searching; search patterns; database characteristics; student search skills; library…

Describes the Dewey Online Retrieval System (DORS), which was developed at the University of California, Los Angeles (UCLA), to experiment with classification-based search strategies in online catalogs. Classification structures in automated information retrieval are discussed; and specifications for a classification retrieval interface are…

A factor analysis of affective data gathered from searchers of an online library catalog, and a card catalog allowed researchers to isolate factors leading to success or failure in information retrieval. Factor patterns serve to identify how searches are evaluated by users. Further research is suggested as are features to facilitate successful…

Describes a study conducted at the University of Illinois to test the effectiveness of subject access in the online bibliographic catalog. Relevance is examined and possible methods of improving subject access are described. Results suggest that significant improvements are not possible within the constraints of existing subject cataloging…

Describes the use of MultiLIS, a fully bilingual integrated library-management software package, at Laurentian University. The authority control module is explained, its potential as a control system for multilingual or multithesaurus controlled vocabularies is considered, and an evaluation of the MultiLIS authority module is presented with…

In 1981 and 1982, the Research Libraries Group (RLG) and four other organizations participated in a coordinated study of public online catalog users and nonusers. Standard, self-administered questionnaires were used to gather data from 8,094 users and 3,981 nonusers in 31 research, academic, community college, public, and governmental libraries…
