Repository access note: Selected sources are linked on individual entries. NYSL newspaper dates summarize service-copy microfilm holdings, not a continuous run or the newspaper’s entire publication life; follow the link for exact issues and gaps. Court surveys describe county holdings and may require advance arrangements. Historical NYG&B microfilm listings refer to a collection transferred to NYPL; confirm current availability there. These sources do not promise online images or complete county coverage.

Sources: the catalogs and repository descriptions linked on the entries above. Selected inventories do not establish complete coverage of every record type or online access to original documents. Read the repository access note for source dates and limitations.

Research tip

New York took state censuses in years ending in 5 from 1825 to 1875, and in 1892, 1905, 1915 and 1925. Many survive at the county clerk's office and fill gaps between federal censuses.
