The five critical years in the development of OCLC (1951-56), the culmination of a century of cooperation between Ohio's colleges and universities, are used to underscore its expansion into a bibliographic utility interconnecting 2400 institutions in the United States and Canada. There are 19 references. (RAA)

Describes a transaction log analysis of the New York Public Library research libraries' OPAC (online public access catalog). Much of the remote searching occurred when the libraries were closed and was more evenly distributed than internal searching, demonstrating that remote searching could expand access and reduce peak system loads. (Contains…

Discusses an increase in library users providing services for themselves that were formerly provided by library staff, and describes a study conducted at Ohio State University that measured (1) the public's acceptance of patron-initiated renewals and other capabilities, and (2) the resulting impact on staff activity. (five 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…

Discussion of the influence of library catalog use studies on cataloging codes and practices focuses on a study of reference staff members at three Association of Research Libraries academic libraries that was conducted to determine their use of bibliographic record elements. Records in online catalogs and bibliographic utilities are examined, and…

Describes a study conducted at Ohio State University that used data obtained from the interlibrary loan process to determine why some users failed to find existing entries in the online library catalog. User errors as opposed to catalog errors are examined, and implications for bibliographic instruction are suggested. (eight references) (LRW)

Reports on the results of two experiments testing the effectiveness of a concept-based computer tutorial for OPAC (online public access catalog) users. Factors that may have caused differences in results, including OPACs used in the experiments and the participants' different ability levels, are discussed. Findings are related to similar studies.…

Describes results of a survey conducted at Indiana State University libraries that studied patron perceptions and demographics related to keyword searching on LUIS, the online public access catalog (OPAC) available through NOTIS (Northwestern Online Total Integrated System.) Demographics studied include age, status, frequency of LUIS use, and…

Results of study on patron information retrieval success and patron use patterns at Ohio State University show that 90 percent of online users preferred online to card catalog; 64 percent of those who tried online catalog switched to it; and patrons used the online more than the card catalog. References are provided. (EJS)

Suggests that libraries abandon full cataloging in favor of indexing, using the information provided by micropublishers. While a national index to the contents of microforms would be best, an alternative for local libraries would be to create their own COM (computer output microfilm) index. Twenty references are included. (Author/RAA)

Findings of a longitudinal study indicate high success rates for OCLC as a source of cataloging copy. They further suggest that holding patterns for many types of materials may be unnecessary. (Author/RAA)

Presents procedures and statistics for a manual inventory and an inventory coordinated with conversion to an online circulation system at University of Kansas main library. Results of this two-phase inventory (Dewey Decimal-classified materials, LC-classified materials) and the cost-effectiveness of such a project in a large library are…

Academic and research libraries have tended to dominate change and codification in this area of library work, as much in 1876 as in 1976. (Author)

Review of research on online public access catalogs sponsored by Council on Library Resources notes the scope and method (questionnaires administered to catalog users and nonusers in 29 participating institutions) and findings and applications (including organizational setting and computer system, catalog use and satisfaction, and implications).…

This essay addresses issue of uniformity or consistency in application of subject headings--as distinct from consistency among headings--to books on any given topic. Discussion covers purpose of subject headings or descriptors, reliability of choices made by catalogers when assigning subject headings, and card and online catalogs. (18 references)…
