    Abstract
    Librarians responsible for organizing access to library collections have an obligation to plan for the future. Developments in the world of information which will inevitably have an impact on how they do their jobs include new forms of media, new cataloguing tools and standards, and new methods of creating, acquiring, and searching for data. Equally if not more important, new models are needed for the range of services which bibliographic control units are working to provide, and for the roles which these units will play in the larger organization

    Abstract
    Evaluative and comparative studies of catalog data have tended to focus on methods that are labor intensive, demand expertise, and can examine only a limited number of records. This study explores an alternative approach to gathering and analyzing catalog data, focusing on the currency and consistency of controlled headings. The resulting data provide insight into libraries' use of changed headings and their success in maintaining currency and consistency, and the systems needed to support the current pace of heading changes.

    Abstract
    This paper looks at one approach to controlling costs when seeking cataloging copy. A small task group in the University of Minnesota Libraries Technical Services Department conducted a study to devise the most cost-effective strategy for searching for and importing bibliographic copy, by compiling costs and benefits of importing records from the OCLC Online Computer Library Center database, the Research Libraries Group Union Catalog (RLIN), and the Library of Congress (LC) catalog. Results of the study indicated that, although the LC database is smaller than the other two utilities, a sufficient portion of needed records were available from LC to more than offset the cost of re-searching in the other databases for records not found. In addition, due to differences in pricing structure, searching RLIN second was found to be more cost effective than going next to OCLC, even though a slightly larger proportion of items were found in OCLC than RLIN. This study may prove useful either as a research method or in terms of its findings for other libraries wishing to compare sources of cataloging copy.

    Abstract
    Many kinds of structure can be discerned in the headings and rules governing the Library of Congress Subject Headings. By addressing these structures at different levels, librarians can develop different approaches to the machine-assisted validation of subject headings, from the checking of individual words to the validation of complex forms of heading/subdivision compatibility. Using computer programs to assist with maintenance of subject headings is becoming increasingly necessary as technical services librarians strive to create consistent and useful patterns of subject collocation in library catalogs
