The "Documents on Documents Collection" consists of documents produced by a variety of organizations in the course of administering state document depository programs. This collection, which contains 166 documents gathered between 1980 and 1983, originated as a resource for administrators of such depository programs and for those establishing or amending such programs. It is intended to provide a broad understanding of the components and procedures required to sustain an efficient state depository. The collection is arranged by state and is subdivided by broad categories: (1) bibliographies of bibliographies and reference tools; (2) letters of transmittal and commentaries; (3) depository contracts; (4) forms and form letters; (5) labels; (6) legislation and legal materials; (7) mailing lists, lists of depository libraries, and lists of advisory councils; (8) manuals; (9) procedural guidelines; (10) promotional materials; (11) selection lists and basic or core lists; (12) shipping lists; and (13) studies, surveys, workshops, and miscellaneous. Thirty-one states and the Virgin Islands are represented. This collection is being maintained on a current basis (i.e., 1983 and forward). The introductory material describes how to obtain the "current" Documents on Documents Collection. (Author/THC)
