Guide to the OSU Libraries map and aerial photography collection.

What's in the Maps collection?

The 3rd floor Maps area is where the general circulating maps are located. Most cases are unlocked, and you can look for the maps you need yourself. Some of the maps in this area are in the online catalog, but others are only listed in the physical card catalog, so you may need to look for call numbers in both places. Assistance with these can be obtained from the Information Desk on the main floor.

Topographic Maps

  • U.S. Geological Survey 7.5' topographic maps ('topos') are arranged alphabetically by the name of the sheet within the appropriate state. To find the name of the sheet, you must use the topo map indexes for the state (on Reference table near the collection). Folders are indexed on the cards inside the lid of each case.
  • Special editions of national park topos are arranged by call numbers. To find the call numbers, look up the park by name in online catalog.
  • Be aware that these maps are a legacy collection; except in special cases paper maps are no longer updated. The official US Topo Quadrangle maps are now online, and are updated every 3 years. The previous online (legacy) quads are then moved into the USGS Historical Topographic Map Collection.
