The administrative correspondence of the Harvard University Herbaria is divided into two collections, the Historic Letter Collection and the General Administrative Correspondence Collection.
The Historic Letter Collection consists primarily of the personal correspondence of Asa Gray dating from 1830 to his death in 1888. The collection also includes letters to Sereno Watson and other members of the Gray Herbarium staff from 1870 to 1906.
The General Administrative Correspondence Collection represents the work of the various Gray Herbarium directors and other herbarium staff from 1890 to 1960. The letters document herbarium business with Harvard administration and suppliers, the collection and exchange of specimens, and scientific communications from other botanists, prospective students, and amateurs.
These two collections have been combined in the correspondence list below. Contact the archivist if you have any questions about individual letters or correspondents.
Additional administrative records can be found in the personal papers of the herbaria directors and at the Harvard University Archives.
