Among the print and online sources we consulted were local phone directories and an index to the Arizona Daily Star (Tucson newspaper). The last listing for the Cox Library was in 1966, with an address of 302 W. Elm Street, and a phone number of 622-6410 (at that time the area code was 602). We do not have any information on what happened after that.
The Joel D. Valdez Main Library has the Cox Collection for the Pacific and Rocky Mountain States on microfilm. Unfortunately, we do not know what became of the rest of the collection.
