Welcome to the Hoffman Research Library 


The Hoffman Research Library (HRL)  is located at the Minnesota Genealogy Center in Mendota Heights, Minnesota. It is a destination research facility for the Midwest region, with unique resources for studying family history. The 30,000+ items contained in the HRL collection  represent the state of Minnesota; all its individual counties and larger cities; all of the fifty states of the United States plus specialized regions (e.g. New England); and a wide spectrum of nationalities and countries from around the world. The depth of coverage varies across states and countries, and many items are in their language of origin.

Library Volunteers

Volunteers are needed to staff the Minnesota Genealogy Center during public hours. Duties include opening and closing the Center, answering the phone, and helping walk-in patrons find their way around the Hoffman Research Library. New volunteers are required to complete an in-person training class. Then, they are paired with an experienced volunteer to learn the ropes. No experience is necessary.

If you have an organizational mindset, volunteers are also needed for our collection cataloging project. We are converting to the Dewey Decimal System, and welcome help from those who enjoy categorizing and describing materials for easier retrieval by our researchers. You need not have special training - we will teach you the ways of Dewey and our online catalog.

Please consider regularly giving a few hours - we can't do it without you!
