The Arizona Index was created and maintained by the University of Arizona Libraries Central Reference Department, indexing began in 1951 and continued until 1990.
The Arizona Index brings together all of the citations of all periodicals articles about the state of Arizona. The Index was maintained in card catalog form, the cards arranged by broad subject. Some entries in this card catalog index include items dated as late as 1990, the year all indexing efforts for this project ceased at the University of Arizona Library. In earlier years, a small number of libraries in the state subscribed to copies of the typed cards; these libraries then maintained their own “catalog” of the Index. Then in 1978 the Arizona Index was printed in a two-volume publication issued through G.K. Hall. That publication is long out-of-print. The online edition presents exactly what was compiled for the published volumes and adds the citations that were completed to 1990 which were not included in the printed edition.
