RCHS manages and administers the largest local history library, archives and research center in Rensselaer County. These collections, comprising more than 33,000 items, are the fastest-growing and most well-used at RCHS. All collections are non-circulating.

Our library is frequented by researchers of all ages and interests. From genealogists who come to fact-check and legitimize their journal articles to local Trojans curious about the history of their homes, we offer an extensive collection of volumes, documents and artifacts to support your studies. Many a storyteller has camped out in our stacks, gathering details to animate their books and films. We also welcome primary and secondary school students who utilize our research library for research as part of their curriculum.

RCHS is also the repository for the Rensselaer County Surrogate Court Records, 1791-1915. These documents are often a great asset to researchers. Records from 1915 to present day and later records are at the Rensselaer County Surrogate Court. 

Copies of original source documents (from 1791 to 1915) can be requested from the Rensselaer County Historical Society. The fee ($30 per file/$25 for RCHS and TIGS members) covers the cost of pulling a single file from the archives, as well as photocopying ALL documents in that folder and mailing a complete package to the requester. To order a Surrogate Court file, print out the (click:) form and mail it with payment to RCHS.

Please allow 6-8 weeks for processing.
