Book lending is the practice of borrowing books from a library or an individual. Libraries, such as public or school libraries, allow members to check out books for a specified period. This system promotes literacy and access to information without the need for purchasing books. Individuals can also lend books to friends or family, fostering a culture of sharing and discussion. Book lending encourages the circulation of literature, allowing more people to enjoy various genres and authors. It helps reduce waste and supports the idea of reusing resources within a community.
