Proposes an operational definition of relevance for a Web-based library catalog. Proposes measures that characterize user behavior while searching a Web-based library catalog. Develops a methodology to predict when a user's search will be perceived to be relevant by the user. Tests the methodology with over 900,000 user search sessions with the…

Examines usage scenarios for a database of descriptive information to access networked information resources such as online library catalogs, file archives, online journal article repositories, and information servers. Existing classification schemes and their usefulness for networked information resources are discussed. Specific data elements…

Microcatalog use studies at the University of Oregon have demonstrated that users encounter access difficulties when confronted with a multiple file microfiche catalog. This research verifies theories by Mooers, Zipf, and others that the public minimizes search efforts and implies that closed catalogs with supplements such as add-on catalogs will…

Describes a study which compared patron success in finding the same group of titles in the online catalog and the card catalog in two department libraries at Ohio State University. Reasons for patron success and failure with the online catalog are outlined and discussed. Five data tables are included. (Author/JL)

Examines three aspects of keyword searching as a possible solution to subject search problems in online public access catalogs (OPACs). Discusses search results, user satisfaction, and how keyword searching and controlled vocabulary searching are offered in OPAC interfaces. Concludes that keyword searching and controlled vocabulary searching…

Analyses of the success-failure rates and user reactions using four public access online systems indicate that users overwhelmingly preferred the online to manual systems. Improved subject access emerged as the salient feature requiring improvement. Seven references are included. (Author/RAA)

This study was undertaken at the University of Wisconsin-Madison to ascertain if a relationship exists between the kind and amount of information given for a specific item and the access point selected by the searcher to determine its availability. Data, study questions, and four references are included. (Author/CHC)

Explores the influence of several search task characteristics on children's success in finding science materials on an automated library catalog. Findings suggest that the complexity of the search task and the level of children's science domain knowledge affect their success in identifying books on assigned science topics. (Author/AEF)

Suggests improvement to online catalogs based on a 2 1/2 year study of patron search patterns. Preliminary findings indicate significant differences in search strategies and suggest that these strategies and the reasons patrons choose them should be important factors in the design of future online catalogs. Fourteen references are included.…

Research conducted at Fisher Library, University of Sydney, which measured user failure to locate known items in catalog or on shelves, yielded overall failure rate of 35.9 percent (26.2 percent at catalog; 46.1 percent at shelf). User errors caused two-thirds of failures at catalog and more than half at shelf. Fifteen references are provided.…

Reports results of a material-availability study in which library users were surveyed to determine their success in obtaining materials. Both OPAC users and CD-ROM journal-index users were studied and transaction logs verified their self reports. Recommendations for reducing search failures are discussed. (Author)

User-centered design of catalog records requires the study of user behaviors and cognition related to interaction with the catalog. During 3 phases of a pilot study, 103 catalog users described 386 searches; searchers generally knew the title, publication date, page numbers, and/or the author. (Author/AEF)

Compares traditional cataloging to Web-based. Discusses intellectual-access issues as they apply to reference services today, and outlines deficiencies in traditional cataloging, and corresponding attributes of Web-based intellectual access. Notes ways that catalogers and public-service librarians can address these issues. (Author/AEF)

The effectiveness of current subject cataloging practices for assigning geographical headings to local historical records in meeting the requirements of an escalating number of genealogist-patrons was examined. The findings indicated that catalogers use two general approaches in determining subject headings for local historical collections in the…

The Internet is a network of networks which continually accumulates and amasses information, much of which is without organization and evaluation. This study addresses the need for establishing a database of Uniform Resource Locators (URLs), and for collecting, organizing, indexing, and publishing catalogs of URLs. Librarians and information…
