In 1922, an index was assembled of the references to Indians in the Connecticut State Library.

This 186 page index covers the five hundred ninety nine documents which were selected about 1845 from the files of the General Assembly by Sylvester Judd, author of the History of Hadley, Mass. and arranged in two volumes of Connecticut Archives known as Indians.

Entries include petitions, court actions, land transactions, accounts, agreements and in some cases, genealogy when it pertains to the issue at hand.
