what is a library

A library is a collection of resources in various formats, such as books, periodicals, manuscripts, recordings, and films, that is organized by information professionals or other experts. It is a place where literary, musical, artistic, or reference materials are kept for use but not for sale. Libraries can be physical or virtual spaces and may be organized and maintained by public bodies, institutions, corporations, or private individuals. In addition to providing materials, libraries also offer the services of librarians who are trained experts in finding, selecting, circulating, and organizing information, as well as interpreting information needs and navigating and analyzing large amounts of information with a variety of resources.
