New York State Historical Documents Inventory

The Historical Documents Inventory (HDI) is the result of a statewide project overseen by the New York State Archives that inventoried records in institutions throughout New York State that hold historical materials (not including books). Between 1978 and 1993, the New York Historical Resources Center surveyed institutions to locate, identify, describe and report all of the manuscripts and archives materials in New York State repositories that are open to the public, including historical agencies, public libraries, and colleges and universities.
