This annual report describes the activities of the Commission on Preservation and Access, a private, nonprofit organization that works through existing institutions and groups to foster, develop, and support collaboration among libraries and allied organizations in order to ensure the preservation of the published and documentary record in all formats, and to provide enhanced access to these records. The first of 12 sections, the introduction to this report highlights a multifaceted initiative undertaken by the preservation community under the leadership of the National Endowment for the Humanities' (NEH) Office of Preservation to preserve over three million brittle documents over a 20-year period. In the second section, a special report by the Technology Assessment Advisory Committee (TAAC) outlines the preparation of a series of analytic and conceptual papers that will explore options for reformatting preservation copy and the rapidly developing telecommunications technologies. The remaining sections focus on: (1) the organization, support, and 1989-90 initiatives of the Commission; (2) archival preservation; (3) preservation research; (4) librarian and archivist education; (5) the Brittle Books Program; (6) the selection-for-preservation process; (7) the International Project; (8) institutional programs; (9) the collaboration of the Commission with other preservation-related programs; and (10) the dissemination of information by the Commission to preservation audiences.
