In the modern information society libraries have a new role and there are various types of library models.

Library and information science has endeavoured down through the ages to the present time to fulfil the needs of library users.

Library science, not to be confused with librarianship (non-science), is an interdisciplinary science incorporating the humanities, law and applied science to study topics related to libraries, the collection, organization and dissemination of information resources and the political economy of information. Historically, library science has also included Archival science. "The distinction between a library and an archive is relatively modern".
