The Pennsylvania State University Libraries are home to over 400,000 maps.
The Donald W. Hamer Maps Library in 1 Central Pattee Library (basement) holds topographic maps in addition to many other kinds of maps such as nautical charts, tourist and road maps, atlases, gazetteers and more.
The Earth & Mineral Sciences Library holds some Pennsylvania Topographic maps as well as Geological maps.
Historical maps, from before 1900, are housed in the Special Collections Library on the first floor of the Paterno Library.

You can also limit your search by format type in the advanced search screen. In the drop-down menu for Material Type, select "Map" Note that doing this may eliminate some potentially useful resources, because you will be eliminating maps that are not in sheet map form, such as those in books.

Tip! When you have located a map using the CAT, be sure to write down the entire call number and its location. If the map is located at a campus or branch other than the one you normally visit, you may request that it be sent to your location by clicking on the blue "I Want It" button
Preliminary Geologic Atlas of Pennsylvania
Maps are black & white at a scale of 1:62,500 and are listed by quadrangle name. If you don't know the name of the quadrangle, you can use this index to Pennsylvania quadrangle maps to determine the name or look it up using the GNIS (Geographic Names Information System).

Digital Index Maps for some foreign countries are available to help you find the maps you are looking for. The Index maps point to paper maps mostly, but as we digitize more and more maps they will point to digital maps more frequently.
The Maps Library has links to numerous online topographic maps:
The USGS Store enables you to download the most recent quadrangles across the United States. Different scales are available.
To find maps using GeoRef, it is best to use the keywords/anywhere selection from the drop-down menu and type in: [place] AND maps (example: Harrisburg AND maps). If you want to limit to a certain type of map you can include terms such as "geologic or topographic" More information on search techniques is available in the GeoRef help files.

The libraries also have online access to the Serial Set Maps (1789-1969). The serial set contains House and Senate Documents and reports as well as Senate Executive Documents and Reports. The serial set maps are of historical significance, and were previously very difficult to access. The maps have been scanned at high resolution in both black & white and color.
There are two ways to access the maps in the Serial Set:


Fire insurance maps show the outlines of buildings along with their construction details (e.g., brick, wood, etc.). One of the most prolific publishers of fire insurance maps in the United States was the Sanborn Company. Find fire insurance maps in the catalog by browsing or searching for Insurance, Fire - [location] - Maps.
