A searchable compilation of records that identify individual enslaved persons and enslavers in the states of New York, Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut and New Jersey. NESRI indexes census records, slave trade transactions, cemetery records, birth certifications, manumissions, ship inventories, newspaper accounts, private narratives, legal documents and many other sources.

The index contains over 35,000 records and it is expected to grow as John Jay College professors and students locate and assemble data from additional sources.
