After nearly 60 years of collecting, Sid Lapidus ’59 has presented to the Library more than 2700 volumes representing the fruits of his enthusiasm.

The main focus is texts and documents relating to the American Revolution, its run-up dating back to the Commonwealth men, and coming down to documents of the early Federal government.
