Considers some of the major technical and organizational issues involved in virtual-catalog production, contrasting them with the traditional union catalog approach exemplified by COPAC, an online public-access catalog composed of academic libraries in the United Kingdom. Suggest a method of integrating these two models of the union catalog.…

To study the format, content, and rationale of public catalogs used at the University of California at Los Angeles (UCLA) libraries, a questionnaire was sent to each of the campus libraries. The data collected included information on: 1) number of volumes in the library's collection; 2) number of drawers in its catalog; 3) physical arrangement of…

This project proposed to develop and test the use of microform catalogs produced from computer-generated magnetic tape records in both fiche and film formats. The Computer Output Microform (COM) catalog developed for this purpose is a union list of titles from the five participating libraries--Houston and Dallas Public Libraries, Texas State…

Seventy-two libraries participated in the development of a cost model for library catalogs, considered alternate forms of catalogs (including various combinations of card, computer output microfilm, and online), and prepared input data for computer runs to arrive at costs. Card catalogs appeared to be the least costly. (FM)

Discusses the results of responses from 63 academic libraries about the choice and content of their default home Web pages. Shows that some branch libraries display a main library Web page as the default home page for their public computers, while others display a branch library page. (Author/LRW)

Describes the results of a survey of public service librarians conducted by the Queens Borough Public Library to determine their confidence levels of using electronic resource to answer reference questions. Results demonstrated high confidence levels in using the library's online catalog and lower confidence in using the Internet. (Author/LRW)

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)

The Institute of Library Research converted to machine-readable form over one million catalog cards representing about 750,000 Roman-language titles catalogued by the University of California (UC) libraries from 1963 to 1967. From this data base they printed the UC Union Catalog Supplement (UCUCS-1). From 1968 to 1972, an additional set of card…

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)

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…

Though recent technological developments have promised solutions to the costly problems of expanding card catalogs and changing cataloging practices, at the University of California libraries the problems have been compounded by a desire to stay compatible with the changing conventions of the Library of Congress and by an increasingly stringent…

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)

Explored user perceptions of dependability and accuracy of Texas A&M library services through focus groups. Reports user difficulties in locating materials, inaccurate catalog and circulation records, inadequate signage, searching the online catalog, and late notification of interlibrary loan arrivals; and discusses the library's efforts to…

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)
