Boston Libraries by the Numbers
Boston Public Library (BPL)
The Boston Public Library is the crown jewel of Boston's library landscape and one of the most important cultural institutions in the United States. Founded in 1848, it was the first large, free municipal library in America and continues to set the standard for public library service.
Central Library at Copley Square
BPL's Central Library occupies two connected buildings in Copley Square: the historic McKim Building (1895) and the modern Johnson Building (1972). The McKim Building is an Italian Renaissance Revival masterpiece featuring Bates Hall (a grand reading room with barrel-vaulted ceilings), the Sargent Gallery (with John Singer Sargent murals), an interior courtyard modeled after a Roman palazzo, and rare book collections including a Shakespeare First Folio.
Branch Libraries
BPL operates 24 neighborhood branches across Boston, from Allston/Brighton to West Roxbury. Each branch offers free WiFi, public computers, children's programs, book lending, and community meeting spaces. Many branches have been recently renovated with modern technology and expanded programming spaces. The Rabb Lecture Hall at Central Library seats 500 for major events.
BPL Hours
Central Library (Copley Square): Monday–Thursday 9 AM–9 PM, Friday–Saturday 9 AM–5 PM, Sunday 1 PM–5 PM. Branch hours vary, with most open Monday–Thursday 10 AM–6 PM and Saturday 9 AM–5 PM. For exact hours at every branch, check our Boston library hours page.
Massachusetts Residents: BPL participates in the Minuteman Library Network and the Massachusetts Library System's statewide reciprocal borrowing program. If you have a library card from any Massachusetts public library, you can use it at BPL to check out books and access services. This means over 6 million Massachusetts residents have access to BPL's 23 million items.
Harvard Library Access
Harvard Library is the oldest academic library in the United States (founded 1638) and the largest university library in the world, with over 17 million volumes across more than 70 individual libraries. For non-Harvard affiliates, access is limited but not impossible:
Widener Library
Harvard's iconic main library, the Harry Elkins Widener Memorial Library, sits at the heart of Harvard Yard. It holds 3.5 million volumes and is the centerpiece of the Harvard Library system. Access is restricted to Harvard ID holders, but non-Harvard researchers can apply for a Special Borrower's Card through the Harvard Library Privileges Office (fee applies, typically $100+/year).
Lamont Library
Lamont Library is Harvard's primary undergraduate library and one of the few 24-hour libraries in the Boston area (during the academic semester). It features open stacks, group study rooms, a cafe, and the Woodberry Poetry Room. Access is limited to Harvard affiliates, but the building exterior and Harvard Yard are open to visitors.
Public Access Options
Several Harvard libraries have some public access: the Harvard University Archives and Houghton Library (rare books) accept researchers by appointment. The Harvard Art Museums Library, the Harvard Map Collection, and the Cabot Science Library may allow walk-in visitors during certain hours. The Harvard Divinity School Library (Andover-Harvard Theological Library) offers community borrowing privileges.
