The Master of Library and Information Science (MLIS) is the master's degree that is required for most professional librarian positions in the United States and Canada.The MLIS is a relatively recent degree; an older and still common degree designation for librarian to acquire is the Master of Library Science (MLS), or Master of Science in Library Science (MSLS) degree. According to the American Library Association (ALA),"The master's degree in library and information studies is frequently referred to as the MLIS; however,ALA-accredited degrees have various names such as Master of information studies, Master of Arts, Master of Librarianship , Master of Library and Information Science,, or Master of Science. The degree name is determined by the program. The [ALA] Committee for Accreditation evaluates programs in Library and Information Studies,not based on the name of the degree. Admission to MLIS programs normally requires holding a bachelor's degree in any academics discipline, and library schools encourage application from people with diverse academics backgrounds. In the United Kingdom it is more common for a vocational degree in library and information science to bear the standard designation MA or MSc. In the most commonwealth universities, bachelor's and master's programs have been merged to create the MLIS/MLISc degree. IFLA committees have discussed global standards for librarian credentials.
