About Your Library

Welcome to the Peterborough Public Library. Peterborough residents are invited to visit the Main Branch of the library in downtown Peterborough or the DelaFosse Branch in the south end of the city. We are pleased, as well, to serve residents, visitors and guests through this website – our online Third Branch!

Our mission: The Peterborough Public Library is our community's connection to a world of resources to inform, inspire and enlighten.  We make these resources available in a variety of formats and technologies. We also offer a range of programs and services to every age.
