The mission of the Carnegie Library for Local History is to collect, protect, and make available for research, materials in physical and digital formats relating to the history of Boulder County with a special emphasis on the city of Boulder.
The Carnegie Library collects, preserves, and provides research materials relating to the history of Boulder County with a special emphasis on the city of Boulder. The collections focus on original and secondary physical and digital materials about the people, real estate, events, and businesses in Boulder’s history. The Carnegie Library collections include documents, photographs, maps, microforms, oral history interviews, dated newspaper clippings pertaining to a single topic, scrapbooks, ephemera, books, pamphlets, architectural drawings, periodicals and digital files. These collections are valuable historical resources, intended to be protected in perpetuity. Their care and preservation for the use of present and future generations is the principal responsibility of the Carnegie Library.
Scope of Collections
Historically significant materials relating to the city and county of Boulder will be accessioned into the archival collections. Any item selected for the archival collection must undergo assessment to determine its suitability for inclusion. Archival collections focus on materials with local, regional, and enduring value and represent the social, political, cultural, and economic history of the city and county of Boulder.
The archival component of the collections emphasizes the history of the area. Carnegie collects historic records of area businesses, community and civic organizations, religious institutions, and other public or private groups which have influenced Boulder’s development,
or have had a significant impact on the city and county of Boulder and its citizens. Selection of archival materials is assigned to the Carnegie Library archivists and is at their discretion whether materials will be added to Carnegie’s holdings.
In general, the collections are limited to images and documentary materials that support Boulder County history. Artifacts and other objects deemed to have a significant relationship to other items in the collections may be donated to the Museum of Boulder.
Types of items collected:
- Documents (correspondence, diaries, notebooks, )
