The Portland Library Society (1763–1826) or Portland Library was a subscription library in Portland, Maine. The library "was originally established in 1763. It was revived in 1786, and re-established in 1806." Samuel Freeman served as librarian ca.1785-1807; followed by Oliver Bray (ca.1812-1817). New members were elected. The annual fee for each member was "two dollars per year in 1784 and fifteen dollars by 1801."
