Genealogy & Local History

Visit the Della Lang Room

Researchers of every experience level are welcome. Our local history collection covers local families, businesses, schools, churches, organizations and community events, with family histories, indexed materials and microfilm — whether you're tracing your family tree, researching a historic property or learning about regional history. Find specific titles in the library catalog ↗.

The Northwest Branch is a FamilySearch affiliate library, with access to FamilySearch digital collections that are otherwise available only at a family history center.
