Arizona State and Local Government Documents Collection
The State and Local Arizona Documents (SALAD) collection contains documents published by the State of Arizona, its Counties, incorporated Cities or Towns, or affiliated Councils of Government; documents produced under the auspices of a state or local agency, board, commission or department, including reports made to these units; and Salt River Project, a licensed municipality. ASU is a primary collector of state publications and makes a concerted effort to acquire and catalog most materials published by state and local governmental agencies.
The ASU Digital Repository provides access to digital SALAD publications, however the ASU Libraries’ non-digitized Arizona documents can be searched through the ASU Libraries Catalog. For additional assistance, Ask A Government Documents Librarian.
Publications issued by the Morrison Institute for Public Programs at Arizona State University are also available in PRISM, in the Morrison Institute for Public Policy - Publications Archive collection.

In 2006, Arizona enacted legislation that directed the Arizona Geological Survey (AZGS) to map earth fissures in the state, required that the presence of earth fissures be disclosed in real estate transactions, and that the resultant earth fissure maps be made publicly available. In order to meet these statutory requirements, AZGS developed, for the first time, standards, procedures, and criteria for identifying, mapping, and characterizing earth fissures.
AZGS geologists identified earth fissures through a review of publications and reports, air photo analysis, and field reconnaissance. Using GPS, we collected relatively high-precision locations and descriptive data along the length of earth fissure surface exposures, and categorized them as either continuous or discontinuous. If we were not able to find and map previously reported fissures, we used the “reported, unconfirmed” category.
