So that enlightenment and literacy may flourish in our community, the Cambridge Public Library dedicates itself to collecting and distributing an array of information and ideas that is diverse in material, varied in formats, and rich in viewpoint, reflecting the multicultural character of the community and world it serves. The Library provides free, equal, and confidential access to its resources and services. Essential to this mission is the active promotion of library services, collections, and programs.

We look forward to serving you in person, at any of our seven locations throughout the City, or through our web site.
