High Quality Content by WIKIPEDIA articles! A librarian is a person who works professionally in a library, and is usually trained in librarianship (known either as library science or library and information science). Traditionally, a librarian is associated with collections of books, as demonstrated by the etymology of the word "librarian" (< Latin liber, `book`). The role of a librarian is continuously evolving to meet social and technological needs. However, a modern librarian may deal with information in many formats, including books, magazines, newspapers, audio recordings (both musical and spoken-word), video recordings, maps, manuscripts, photographs and other graphic material, bibliographic databases, web searching, and digital resources. A librarian may provide other information services, including computer provision and training, coordination of public programs, basic literacy education, assistive equipment for people with disabilities, and help with finding and using community resources.
