The Law Librarianship Graduate Certificate offers several niches and specializations including foreign and international law, government documents, patents, taxation, computer-related services, administration, and special collections such as archives and antiquarian books. While approximately one-third of law librarians have law degrees, most positions do not require a law degree. Law Librarians work in a variety of settings: law school and university libraries, law firm and corporate libraries, state and federal agency and court libraries, and archives and rare book libraries and hold a variety of positions in both public and technical services. They answer legal reference questions, teach legal research, order and process materials, and may also manage electronic access to library materials. Traditional areas of work include: legal reference, collection development and management, acquisitions, cataloging, etc. The American Association of Law Libraries (AALL) promotes and enhances the value of law libraries to legal and public communities, fosters the profession of law librarianship, and provides leadership in the field of legal information. The University of Arizona School of Information (SI) and the Law Library of the James E. Rogers College of Law offer a two-year fellowship in law librarianship for lawyers seeking to become law librarians. Successful applicants will work 20 hours a week in the law library while pursuing Master of Arts in Library and Information Science.
