Elizabeth "Bettey" Moys was born on the 26th June 1928 in Wickford, Essex, England. She grew up in Kent, attended Chislehurst County Grammar School, and graduated from Queen Mary College in London (1949). One of her first jobs was at the Crayford Branch of the Kent County Library Service. Shortly thereafter, she attended the Northwestern Polytechnic School of Librarianship and helped found the School of Librarianship Students’ Association. Following graduation in 1951, she worked as a reference librarian at the Royal Institute of International Affairs (1951) and as an Assistant Librarian at the Institute of Advanced Legal Studies (1952).
Betty was involved with may professional organisations over the course of her career including the British and Irish Association of Law Librarians (BIALL), the Society of Indexers, the International Association of Law Libraries (IALL), the Chartered Institute of Library and Information Professionals (CILIP), the American Society of Indexers, and the Cataloguing and Indexing Group (CIG).
The Moys Classification Scheme for Law Books was published in 1968. Three subsequent editions have been published since then, with a fifth edition due in late 2012[1]. It is used primarily in legal libraries in Canada, Australia, New Zealand, and the United Kingdom.
