Our main goal is provide supplemental funding for library programs, services and events. Without the work of Friends, our library wouldn’t be able to provide such a wide and popular range of programs for Sammamish families.

Join us September 17th – 18th for our annual used book sale. Find thousands of books, priced from $.50 to $2.00. Children’s titles, adult fiction and non-fiction, vintage books and more. All proceeds benefit the programs we all enjoy. Come early for the best selection!


Your library invites you to join the Friends of Sammamish Library (FOSL). The Friends are volunteers who raise money to provide library events and programs our Sammamish families would not otherwise have. Come help us sponsor programs for your library.


The Friends Of The Sammamish Library invite your inquiries and suggestions. Your feedback is important to the growth of the library programs. Please visit our contact page to submit your information, questions, and suggestions. Your participation is appreciated.
