DONATE TO THE FRIENDS OF THE COS COB LIBRARY to support the 2024 expansion and renovation of the Cos Cob Library. Click Here

All donations go directly to the efforts to expand and renovate the beloved Cos Cob Library and help it continue to be an essential hub of our community. We have secured funding from past donors and the local government, and now we need the citizens of Cos Cob to join the effort to help us reach our final goal and ensure that we break ground this year.

Join us on Sunday June 2, 2024 from 2:00-5:00 PM for our Friends and Fundraising event at the Greenwich Historical Society.

This event is FREE but you must register for tickets in advance.


There will be fun for all with children’s activities, games, story telling and programs. An in-depth presentation about the new library and discussion of the fundraising efforts. Appetizers and snacks and beverages will be offered throughout the event.
