History

The library was built in 1906 with $15,000 donated by steel tycoon Andrew Carnegie. As part of the deal, the City of Boulder agreed to set aside $1,500 each year to maintain the building and the collection. Since the people of Boulder referred to their town as the “Athens of the West,” architect Thomas McLaren patterned the library after a small Greek temple that had recently been unearthed near Athens. The open floorplan allowed librarians to move stacks and furniture in order to meet the demands of a growing collection. The Carnegie Library was able to keep up with the town’s needs until the population doubled and books and patrons began to exceed the space.  When a new library was opened on Canyon Boulevard in 1961, Carnegie’s role in the community diminished and the building began showing signs of deterioration and neglect. In 1981, library staff rallied to regain ownership of the building. With the Colorado collection outgrowing its space at the Main Library, the entire collection of books, maps, oral histories, and documents was moved into the building on Pine Street. In 1983, the Carnegie re-opened as the Carnegie Library for Local History.
