Library sales are events where public libraries sell off surplus or donated books, magazines, and other materials. These sales often occur annually or semi-annually and provide an opportunity for the community to purchase items at low prices. The funds raised typically support library programs and services. During a library sale, patrons can browse through a variety of genres and formats, including fiction, non-fiction, children's books, and audiobooks. Many libraries also offer special deals, such as bag sales, where customers can fill a bag for a fixed price. These events promote literacy and encourage reading within the community.
