Welcome to the Empire Archival Discovery Cooperative

The Empire Archival Discovery Cooperative (Empire ADC) is your source of information about archival collections held in cultural heritage organizations across New York State. At Empire ADC you can search and browse collection descriptions (called “finding aids”) to discover what historical materials are available for your research and where to find them.

Empire ADC is a product of the Empire State Library Network (ESLN). Leadership is provided by an advisory group of archivists from across the state and is administered by the Empire State Library Network and its regional members.
