There is a map collection on the 3rd floor of the Brooks Library. Currently, the collection contains over 90,000 sheet maps for our patron use. That collection contains nearly every 7.5 minute topographic map with a goal of having a complete U.S. topographic collection. We also have several 15 minute maps, but do not have a complete collection.
Types of Maps:
Atlases
The Map Room is also home to many of the Library's atlases. To provide convenience and ease of use, these often oversized tomes are kept in the Map Room. Most of these atlases may be checked out. Check with the staff at the 3rd floor service desk. Atlases are also found in the main book stacks.
