Historical Documents Inventory
The Historical Documents Inventory (HDI) is the product of a vast survey of the holdings of New York State’s historical records repositories. The HDI consists of more than 23,000 catalog records describing archival and manuscript material held by approximately 1,250 historical societies, colleges and universities, municipal historians’ offices, and cultural institutions throughout the state. Given the broad scope, users must be sure to note the location of the materials described in each HDI catalog record and contact the holding repository in order to view records or request copies.
