Cambridge Public Library

The Cambridge Public Library serves as a doorway to opportunity, self-development and recreation for all its residents, and as a forum where they may share ideas, cultures and resources among themselves and with people around the globe. The free availability of information, the lively interaction of people, and the open exchange of ideas animate and extend the democratic mission of the library.

The library is a dynamic, community-oriented system providing excellent services, collections and programs to all members of the community. We are dedicated to affording the people of Cambridge resources for recreational reading, independent learning, and the introduction of children to the world of literacy and learning.

The Cambridge Public Library is designed to work as a unified system with a strong main library and six active branch libraries each tailored to the unique constituencies and needs of its immediate neighborhood.

The Main Library has been located in the geographic center of the city since 1889 and consists of two facilities: the Van Brunt and Howe Richardsonian building constructed between 1889 and 1902 and the new addition which opened in 2009. The Main Library is accessible by both bus and subway.

Collins Branch

Beginning life as the Gale Lumber Company, the Cambridge Public Library's Collins Branch in West Cambridge has been a library since 1936.  Detailed with outstanding oak accents, the floors, doors, and windows are testaments to the workmanship of a day long gone.  The glass in the transom shimmers with age, and the fireplaces give evidence to the building’s beginnings.  Because of advances in other areas, both are no longer used but they still remind everyone who enters the library of its original purpose, its character, and its long association with the neighborhood.  While some value its quaintness above all else, the library is vibrant and dynamic, offering a comprehensive collection of books, DVDs, audio books, children’s materials and magazines.
