Friends Members show continued support for the Library. Becoming a member is an opportunity for community service and involvement in hosting programs and exhibits, shelf reading, and assisting with event hospitality.


The Cos Cob Library is the hub of the local community. Choose from among 40,000 materials including books, movies, magazines, and CDs.

Wifi is available throughout and 12 public computers are available in the building. The Community Room displays art work throughout most of the year and the room is available for local meetings and programs. The Friends of The Cos Cob Library support programs including several book clubs, numerous storytime and craft programs for children, author visits, informative lectures for adults, and much more.

It has often been stated that our library resembles ‘Cheers,’ where everybody knows your name. Visit and see for yourself!
The Cos Cob Library has a long history, with the current building opening in 1999. Long in need of renovation, and following years of exploration, we are excited to finally undertake this vital work.

Your support is essential to bringing this dream to fruition, as we build a new and improved library that will assist in Cos Cob’s daily needs, and also grow with our robust community.

Thank you for your time and efforts in supporting the campaign.
