The collection as a whole is rich in material on the Library, its day-to-day operations, and its growth. Especially of interest are the summary histories in Box 1, information on proposed new buildings, merger plans with the Library of Congress, and the very thorough records detailing Mary L. Marshall's role in the development of the AML Classification.

Minutes of committee meetings which provided the rationale for and made the decision to suspend the Library's production of the Index Catalogue.

Chiefly requests and acknowledgments for/about the Index Catalog.

Typescript notes about data in various libraries and repositories relating to the history of the National Library of Medicine, including its predecessors. Much of the material pertains to the period when John Shaw Billings was librarian.

Correspondence, invitations, greetings and printed matter documenting the Army Medical Library's centennial celebration in 1936.
