In addition to lending books, magazines, and other materials, public libraries also often provide access to electronic resources such as e-books and online databases, and may offer programs and events for children, teens, and adults. The specific services and resources that a public library offers will depend on the needs and interests of the community it serves. Overall, the main goal of a public library is to promote literacy, learning, and personal growth by providing access to a wide range of information and knowledge.
