A Back-to-School Book Sale will be sponsored Sept. 15-25 by the Friends of the Fairfield Public Library at the main library, corner of Old Post and Post roads.

The books will include children’s, young adult, fiction and non-fiction titles. Non-fiction books can be purchased at a “buy-two-and-get-one-free” price.

The selection on sale will change frequently, according to organizers of the sale, which takes place during regular library hours.
