The Longmont Archives contains many documents relating to the history of the St. Vrain Valley. These documents include maps, letters, diaries, business records, City records, and books and manuscripts on local history. Because of the uniqueness and fragility of the items in the Archives, nothing can be checked out.
Copies are available at ten cents a page.
Come to the Archives to discover the past owners of a local house, trace the evolution of a Longmont business, research the first years of the town of Longmont, and much more. The Archives is located on the second floor of the Longmont Public Library, by the Fiction section. The Archives is open 1 to 4 p.m., Monday, Tuesday, and Thursday by appointment. Please call first to discuss the donation and then make an appointment to bring the object or photograph to the Longmont Museum at 375 Kimbark Street. The Longmont Museum accepts objects, photographs and documents that have significance to Longmont and the St. Vrain Valley.
