Sag Harbor’s John Jermain Library was commissioned and built in 1910 by Margaret Olivia Slocum Sage in memory of her grandfather, Major John Jermain, as a gift to the people of Sag Harbor. It was named a contributing structure to the Sag Harbor Historic District in 1973; a light-filled fully-accessible addition, which doubled the space of the building, opened in 2016.
