The Map collection is located in the Northeast part of the third floor of the Brooks Library. Many of the maps are arranged in call number order. It is important to note that the majority of maps are not cataloged, thus may not be found in the online catalog, OneSearch. Those materials that are cataloged are shelved in LC call number \ with the exception of topographic maps which are shelved by State and then alphabetically by Quadrangle name. An index to each quadrangle is available in the first drawer for each state. Other maps include:
There are a few atlases, maps, charts, and other cartographic material that come directly through the federal depository library program (FDLP) and are classed in the SuDocs system. Those items are shelved on the book shelves with the Department of the Interior collection or in Government Publications.
Green Trails Maps - These are high quality recreational 15-minute topographic maps showing the most current trails, road and access to information about national forests, parks, and other public lands.

All are cataloged under the general class G4281.E63.G7 and then shelved alphabetically by their quadrangle name. An index is available to help find the quadrangle area (G4281.E63.G7 Index).
