Carnegie Library for Local History

The Carnegie Library for Local History archive collects and preserves our community’s memory for future generations of researchers. Very few public libraries have collections of local history materials as comprehensive or as exciting as those in the Carnegie Library for Local History. Written, visual and audible materials created by and about Boulder-area residents are housed in our documents room, and are available to the public and scholars for research. Collections documenting early geographic, cultural and social regions of Boulder County include:

  • documents
  • photographs
  • Maria Rogers Oral History Program
  • historic Boulder and Boulder County newspapers in microfilm ranging from 1869-present as well as the Boulder Daily Camera archives organized by last name and subject.

The archive’s resources are non-circulating and must be used in the archive.

Obituaries may be requested by email, [email protected].

Genealogy Resources

Housed inside the Carnegie Library for Local History is the Boulder Genealogical Society’s collection. This collection consists of a wide range of materials including:

  • obituary indexes (1859-1925 and 1960-present)
  • mortuary and burial records
  • histories and directories for various Boulder churches

The Genealogical Society offers research for a fee.  For more information email [email protected].
