Definitions for "Librarians"
To the layperson a librarian is anyone who works in a library, but the designation 'librarian' refers to those members of library staff who have a professional qualification in librarianship. Most librarians are chartered members of CILIP (the Chartered Institute of Librarians and Information Professionals). The other main group of staff who work in the library are library assistants.
