Thematic maps - To find maps or atlases dealing specific subjects in Arizona, first try searching the ASU Libraries Catalog, then try the Map Index.
To find maps that are available in the ASU Libraries Map Collection, you will need to limit your search. While in the advance search mode, change (limit) the location to "Science Library" and the Material Type to "Map."
Many of the older thematic maps available in the ASU Libraries Map Collection are not yet listed in the library catalog. (We are working on it, but there are over a quarter million maps that need to have their records converted to the library catalog.) For Arizona maps, search the library catalog first as the Map Index may provide an outdated call number.
