A Book Exchange is a system where individuals can swap books with one another, promoting the sharing of literature and reducing waste. Participants can bring their unwanted books to a designated location, such as a community center or library, and select new titles to take home. This encourages reading and allows people to discover new authors and genres without spending money. Many communities have established Book Exchange programs, often in the form of small, free-standing libraries or organized events. These initiatives foster a sense of community and literacy, making books accessible to everyone while encouraging a culture of sharing and sustainability.
