The 1974-1976 Additions include correspondence, minutes, proceedings and financial records relating to the administrative offices of the convention and its various subcommittees, panels, and advisory boards. The records have been arranged into five series, with the materials contained in the administrative records, board of trustees and General Committee of Revision sections filed chronologically and the subject file and miscellany organized alphabetically by subject and chronologically thereunder.

Administrative Records (1939-1964) consist of correspondence, minutes, and proceedings of scattered organizational and administrative meetings held by the convention.

The Board of Trustees materials concentrate on the period 1900-1940 and on the 1960s. These records include correspondence, “letters” (circular memoranda), minutes, and financial material.

The series entitled General Committee of Revision documents the internal organizational structure of the USPC and its decision-making processes. Included are correspondence, related reports, and other materials of the many subcommittees, panels, and advisory boards, that comprise the Committee of Revision. Filed under the specific committee subunit are lists of admissions and deletions to the United States Pharmacopeia. Particularly well represented in this series are the Subcommittee on Tests and Standards, the Subcommittee on Sterile Products, the Vitamin Advisory Board (specifically Vitamin B12), and the Subcommittee on Scope and its advisory panels.

Materials incorporated in the Subject File are correspondence, assays, and reports on topics related to pharmacy and pharmaceuticals. This file was a reference source for the administrative offices and subcommittees of the USPC. Of these five series, the subject file comprises the largest group of material on pharmaceuticals. Themes which are especially strong in this category are the Drug Information Service (DIS), international standards, tablet disintegration, and Vitamin D.

Miscellany contains fragmentary and isolated correspondence and reports on a number of agents, agencies, and operational matters which are not directly related to any of the above identified subdivisions of the records.
