This collection contains a wealth of information on the early history of the Smithsonian and the development of the USNM. There is much correspondence with collectors and participants in expeditions in the field. The records are indexed by a card file, as well as individually, in each volume. Letters dated 1875–1877 are indexed as part of the Secretary's records (Record Unit 26), vols. 184-209. Contact the Archives Reference Team for further information about this collection.
