Classification and audiovisuals.

The University of Connecticut Health Center Library's substantial investment in audiovisuals has prompted careful examination of its organization of the AV collection and its effectiveness in answering user needs. While an accession number system worked for a small collection, increased size quickly generated access problems, especially because shelves are open to users. With the present collection of over 2,500 audiovisual items, adoption of the NLM classification promises convenient and continued flexibility in the future.     

A computerized cataloging management system for health science audiovisuals

This paper describes the implementation of the Stanford Public Information and Retrieval System (SPIRES) by the University of Michigan Medical School Learning Resources Center. SPIRES is a bibliographic data base management system which offers on-line search capabilities and retrieval of data in programmable formats. The Learning Resource Center utilizes SPIRES for the interactive retrieval of cataloging data, bibliographical compilations, and book catalog production.     

A union catalog of monographs: another approach

The rationale for and the production of the 1977 TALON Union Catalog of Monographs are described. The 158,859 records include the existing machine-readable records for six health sciences libraries plus the cataloging of six others, converted by matching other data bases and by keypunching. The method and costs of production are discussed. Use of Computer-Output-Microfiche (COM) significantly decreased the cost and time required for publication. The $.076 unit cost per entry, with both author and title access for the COM method, is almost one-half the unit cost for the previous method which offered only main-entry access. The TALON Catalog compares favorably with the Midwest Medical Union Catalog. The addition of the title index significantly increases its usefulness. However, the unique feature of the TALON Catalog may be its machine-readable form which offers the potential for quantitative analyses of health sciences library collections. Such data may be essential for rational management of limited library funds.     

A description of the catalog division project at the College of Physicians of Philadelphia Library.

This paper describes the procedures used at the Library of the College of Physicians of Philadelphia to divide its ninety-year-old dictionary card catalog. The division was necessitated by overcrowding, obsolete subject headings, and lack of a complete authority list which resulted in like materials being scattered throughout the catalog under several headings. Two catalogs were created: the historical-biographical catalog, representing all works published before 1950 and all works of historical or biographical nature; and the current catalog, containing all works published from 1950 on, excepting historical or biographical materials. The 1950- catalog was further divided into name and subject catalogs, and the subject section was revised according to MeSH. The project was completed in about two years. As a result, searching time has been much reduced, and the library is able to take advantage of the annual revisions of MeSH to update the subject catalog.     

Bibliographic control of audiovisuals: analysis of a cataloging project using OCLC

The staff of the Quillen-Dishner College of Medicine Library cataloged 702 audiovisual titles between July 1, 1982, and June 30, 1983, using the OCLC database. This paper discusses the library's audiovisual collection and describes the method and scope of a study conducted during this project, the cataloging standards and conventions adopted, the assignment and use of NLM classification, the provision of summaries for programs, and the amount of staff time expended in cataloging typical items. An analysis of the use of OCLC for this project resulted in the following findings: the rate of successful searches for audiovisual copy was 82.4%; the error rate for records used was 41.9%; modifications were required in every record used; the Library of Congress and seven member institutions provided 62.8% of the records used. It was concluded that the effort to establish bibliographic control of audiovisuals is not widespread and that expanded and improved audiovisual cataloging by the Library of Congress and the National Library of Medicine would substantially contribute to that goal.     

The NLM current catalog

When the National Library of Medicine acquired a computer to augment its publication program, the intent was to present in one medium an index to journal articles and a catalog of books and new serial titles. The computer programs designed for indexing were unsatisfactory for cataloging, however; so two publications were issued, the Index Medicus and the NLM Current Catalog.The Current Catalog features separate name and subject sections, added volumes, and technical reports.The Express Cataloging Service was one of the first attempts to increase the speed and coverage of the Catalog. Shared cataloging with the Library of Congress, the Countway Library at Harvard, and the Upstate Medical Library in Syracuse, New York, have also contributed to the efforts toward improving this library service. An additional shared cataloging program, this time with the National Medical Audiovisual Center, is expected to be implemented shortly.     

The user friendly card catalog

The changing roles and relationships of professional staff in Reference and Cataloging departments in the catalog creation process are discussed. Specific examples are given for handling classification, subject headings and cross references. The article stresses the importance of interface between the two departments in making the catalog more accessible to the users of the library.

Government documents and the online catalog

Prior to planning for implementing the NOTIS system, the Vanderbilt Medical Center Library had not fully cataloged its government publications, and records for these materials were not in machine-readable format. A decision was made that patrons should need to look in only one place for all library materials, including the Health and Human Services Department publications received each year from the central library's Government Documents Unit. Beginning in 1985, these publications were added to the library's database, and the entire 7,200-piece collection is now in the online catalog. Working with these publications has taught the library much about the advantages and disadvantages of cataloging government documents in an online environment. It was found that OCLC cataloging copy is eventually available for most titles, although only about 10% of the records have MeSH headings. Staff time is the major expenditure; problems are caused by documents' irregular nature, frequent format changes, and difficult authority work. Since their addition to the online catalog, documents are used more and the library has better control.     

Survey of the card catalog in medical libraries

A survey of present uses and arrangement of medical library card catalogs was made in order to determine current practices and trends. Attention was focused on the influences of MeSH on the card catalog. The results indicate that the prevalent type of card catalog found in medical libraries is the divided catalog. In addition, it appears that this catalog arrangement is gaining acceptance, and the trend is toward division. MeSH has an effect on the organization of the card catalog; libraries indicate that it is an influential factor in the decision to divide the catalog.

The U.S. monthly catalog and the publications reference file as collection development tools

The 1991 Monthly Catalog of United States Government Publications was examined using a random sample of 668 publications in order to determine what percentage of materials produced at the U.S. Government Printing Office (GPO) were available through the depository library system, and how many of those were offered through the Sales Division via the Publications Reference File (PRF). It was found that 98 percent of publications (655 titles) in the Monthly Catalog were depository items. The remaining two percent (13 titles) are discussed as an indicator of what was not available through the depository system. It was also found that only nine percent of the publications (62 titles) in the Monthly Catalog were listed as available through the Sales Division. Of that nine percent, only 60 percent (37 titles), were listed in the PRF after one year. The nature of these publications and their average prices are examined. Also discussed are the publications dropped from the PRF. A total of 293 publications were identified as available through either GPO or agency distribution, representing 44 percent of the original sample.
