Librarian

A librarian is a person who works professionally in a library, providing access to information and sometimes social or technical programming. In addition, librarians provide instruction on information literacy. They are usually required to hold a graduate degree from a library school such as a Master's degree in Library Science or Library and Information Studies.

Traditionally, a librarian is associated with collections of books, as demonstrated by the etymology of the word "librarian" (from the Latin liber, "book"). The role of a librarian is continually evolving to meet social and technological needs. A modern librarian may deal with provision and maintenance of information in many formats, including: books; electronic resources; magazines; newspapers; audio and video recordings; maps; manuscripts; photographs and other graphic material; bibliographic databases; and web-based and digital resources. A librarian may also provide other information services, including: information literacy instruction; computer provision and training; coordination with community groups to host public programs; assistive technology for people with disabilities; and assistance locating community resources. Appreciation for librarians is often included by authors and scholars in the acknowledgment sections of books.

The Sumerians were the first to train clerks to keep records of accounts. "Masters of the books" or "Keepers of the Tablets" were scribes or priests who were trained to handle the vast amount and complexity of these records. The extent of their specific duties is unknown.
