There are several ways to connect to library catalogs on the Internet: telneting, links via home pages, and online directories. This article discusses Hytelnet and Libgopher, online directories which list available catalogs and make telnet connections to them. Hytelnet is a good resource for OPAC statistics and Libgopher provides keyword…

Assesses the current state of reference structures in online public access catalogs (OPACs) in a framework defined by stagnation, progress, and future challenges. Outlines six areas for reference structure development. Twenty figures provide illustrations. (AEF)

Thirty-one public library users were observed searching the Web and/or a Web-based on-line catalog. Four user categories were identified, distinguished by number of search approaches employed. Results indicate experience and motivation, elements of situational goals and mental models, work in tandem to determine search approaches, Web sites…

This survey of 57 members of the Association of Research Libraries (ARL) examines technical and management issues in providing remote access to their online catalogs, as well as with instructions and services for remote users. It is noted that most ARL libraries have not yet conducted studies to project the extent of use of remote access, although…

One of the recent innovations attempting to catalog Internet resources is a standard for resource description called the Dublin Core metadata set. Discussion includes application of library standards; development of metadata elements; ongoing refinement of the elements; and applying the Dublin Core. (AEF)

Examines some of the incentives behind cataloging on the Internet. Discusses the Dublin Core metadata elements set which attempts to apply traditional cataloging practices to new technologies. Looks at the practicalities of such a system, including three obvious benefits to mapping Dublin Core elements to MARC fields. (AEF)

This study developed an analytical approach to detecting groups with homogenous usage patterns in a Web-based information system. Principal component analysis was used for data reduction, cluster analysis for categorizing usage into groups. The methodology was demonstrated and tested using two independent samples of user sessions from the…

The Dublin Core (DC) metadata standard is emerging as one of the leading initiatives in digitization programs; as libraries, museums, archives and others begin to digitize their physical materials it will be imperative that internationally recognized standards be used. Key elements behind the development of DC, and the 15 fields of DC are…

Describes the latest modifications being made to OASIS, a front-end enhancement to the University of California's MELVYL online union catalog. Highlights include the X Windows interface; multiple database searching to act as an information network; Lisp implementation for flexible data representation; and OASIS commands and features to help…

Presents a methodology for analyzing patterns of usage of a Web-based library catalog and evaluates the methodology with data collected from the transaction logs of the Web interface version of the University of California's Melvyl Systemwide Library Catalog. Results revealed major differences in usage (number of searches, search time, number of…

Describes Web-based online public access catalogs (Web OPACs) and other Web-based tools as gateway methods for providing access to library collections. Addresses solutions for overcoming barriers to information, such as through the implementation of proxy servers and other authentication tools for remote users. (Contains 18 references.)…

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…

Analyzes the change that Internet-based OPACs (Online Public Access Catalogs) have represented to the structure, administration, and maintenance of the catalogs, retrieval systems, and user interfaces. Examines the structure of databases and traditional principles that have governed systems development. Discusses repercussions of the application…

Describes the Electronic Resources Directory of Monash University (Melbourne, Australia), designed for locating electronic resources of the library.
