Librarian from WikiPedia:

A librarian is an information professional trained in library and information science, which is the organization and management of information services or materials for those with information needs. Typically, librarians work in a public or college library, an elementary or secondary school media center, a library within a business or company, or another information-provision agency. Some librarians are independent entrepreneurs working as information specialists, catalogers, indexers and other professional, specialized capacities. Librarians may be categorized as a public, school, correctional, special, independent or academic librarian.

Traditionally, librarians have been associated with collections of books, as demonstrated by the etymology of the word "librarian" (< Latin liber, 'book').
