The Multiple Versions Forum was convened to arrive at a consensus on various aspects of constructing bibliographic records for items that are the same in content but differ in physical representation. The 33 forum participants--representing backgrounds in network systems, national libraries, archives, cataloging systems, USMARC, AACR2 (Anglo-American Cataloging Rules, second edition), microforms, preservation, serials, and special materials--offered varying perspectives to the discussion. The forum focused on identifying and evaluating solutions for the USMARC record-based communications environment. After introductory remarks, the forum began with two framework presentations. The first treated the definition and scope of the multiple versions questions, and the second surveyed the characteristics of various automated environments in which bibliographic data are currently manipulated. From discussions following these presentations, forum participants developed a set of seven working assumptions and a set of nine evaluation criteria for techniques that would be discussed. Following the framework sessions, three basic techniques for handling multiple versions were examined in detail: (1) composite; (2) two-tier and three-tier hierarchical; and (3) separate. Of the options considered, the two-tier hierarchical model was considered the most viable for preservation microform versions. Various aspects of the discussion of the Forum participants on the selected model are presented in six sections, and appended materials include descriptions of the other types of models considered as well as a list of participants and an agenda for the meeting.
