A Library is a collection of books, and possibly other materials and media, that is accessible for use by its members and members of allied institutions.

Libraries can vary widely in size and may be organised and maintained by a public body such as a government, an institution such as a school or museum, a corporation, or a private individual.

Library buildings often provide quiet areas for studying , as well as common areas for group study and collaboration, and may provide public facilities for access to their electronics resources, such as computer and access to the internet.
