Search for maps through the library catalog IUCAT Advanced Search. Enter the relevant location into the Subject box and enter "map or maps" in the All Fields box. As an alternative, you can choose your format in the right-hand column > map and atlas are separate choices. You can also add keywords about the type of map you need (for example: "Geology" or "Interstate 69").
* Be wary of limiting your search by "map" format. Many of our maps have not be encoded as such; instead add "map" as a keyword in your search.
