Recent Developments in the Bibliographie Control of Microforms

Microforms, especially large microform sets, have been acquired, stored, and neglected in libraries for many years and in some cases for many decades. The result has been thousands upon thousands of titles that have little or no bibliographic access. After these years of neglect or minimal treatment, however, microforms have received much attention in the 1980s. Many previously inaccessible microform sets have been, or are in the process of being, brought under bibliographic control. Bibliographic control of preservation microfilming is also an issue that has received much attention in recent years. Success in bibliographic control can be credited to many major projects and activities such as the Association of Research Libraries (ARL) Microform Project, the cataloging of major sets by various libraries, OCLC's Major Microforms Project, and Research Libraries Group's (RLG) cooperative preservation microfilming projects. This article contains discussions of some major accomplishments in the bibliographic control of microforms since the publication of Suzanne C. Dodson's 1983 article, which was based on a paper originally presented at the seventh annual Microforms Conference in Arlington, Virginia (November 16-17, 1981).
