In rapid succession there followed alpha-betized subject indexes to major authors like Aristotle (indexed anonymously by 1250 in Paris), Augustine (by the Dominican Kilwardby at Oxford, 1256–61), or Aquinas (owner- indexed by Godfrey of Fontaines, then circulated more broadly). These indexes used a clear ordering system (the alphabet) and subject terms that were standard in scholastic circles, with the result that they could serve as a col-lective resource for students and scholars throughout Europe who had access to a copy, and they circulated separately from the works they indexed.127
