Established on July 29, 1985, the Montgomery County Archives serves as the institutional memory of the government of Montgomery County, Maryland. The Archives is a repository for permanent records of historical or evidential value created or received by the County government in the course of its business activities. The Archives identifies, acquires, organizes, describes, and preserves historic records of the Montgomery County Government. The Montgomery County Historical Society has been administering the Archives in a reduced capacity since July 2003.
A complete description of the Archives collections is available online at: http://www.montgomeryarchives.org
