This database is a work in progress. Check back frequently for upgrades and updates :)!
Certain assumptions have been made with the creation of this database. First, all documents pertain to the United States in general (unless otherwise stated), and Arizona in specific. Other locations contained within the document are listed in the keywords. Second, all documents are assumed to pertain to geology. Third, general characterisitcs (i.e. mechanics, processes, triggers, etc.) are not listed here unless the references indicated involvement in Arizona. The USGS maintains a searchable bibliographic database pertaining to those issues (click on link at bottom of page).

This database is incomplete, pending addition and acquistion of additional bibliographies. It should also be noted that this database is not yet searchable.
