OSUL Map Collections

The OSU Libraries map collections contain about 300,000 map sheets. Of these, about 70% are included in the Library catalog. The rest of the maps are available but can only be found by asking for assistance or browsing.

There are two major map collections:

The Gardner Family Map Room in Thompson Library contains primarily thematic maps (political/historical), atlases, and international topographic maps.

The Geology Library map collection in the Orton Memorial Library of Geology in Orton Hall contains geology-related maps and the USGS topographic maps for the United States.

Also, there are smaller, specialized map collections in other libraries in the OSUL system.

Map Types

Physical maps display the natural features of the Earth -- the location and names of rivers, valleys, oceans, continents, islands and volcanoes, etc.

Physical maps are the basis for theme maps, and most common maps are a combination of physical and political.

More than half of the sheets in the collections are topographic maps, usually produced by government agencies. They depict relief features, place names, transportation infrastructure, and settlement patterns -- even individual houses are included on many series. For the scholar, topographic maps furnish an extraordinary record of both the built and the natural environment. The Collections' holdings cover the entire world but at different scales for different periods and places. Topographic maps for the United States and its territories and Antarctica are in the Geology Library. Topographic maps for the rest of the world are in the Gardner Family Map Room.

 

Maps focusing on the distribution of features of a particular sort are generally known as thematic maps. The collections hold thematic maps of all types. The Geology Library collection is a depository for GeoScience thematic maps published by the United States Geological Survey and the major geological surveys of Canada and other countries. Individual U.S. State geological surveys are also available. Other thematic maps such as battles, endangered species, history, transportation, etc., are in the Gardner Family Map Room.

Historical maps are a special type of theme map showing a specific time and area. War maps from WWII, the Lewis and Clark Trail, and the Carta Marina are some examples of historical maps.

Nautical Charts are specifically for water travel.

United States Coastal Charts are available from NOAA's Office of Coast Survey. Each chart is updated with current Notices to Mariners.

The Office of Coast Survey's Historical Map & Chart Collection contains over 20,000 maps and charts from the late 1700s to present day. It includes some of the nation's earliest nautical charts, hydrographic surveys, topographic surveys, geodetic surveys, city plans, and Civil War battle maps.

Canadian Nautical Charts can be found here at Fisheries and Oceans Canada.

Paper charts go out of date quickly and can NOT be used for current navigation.The Library of Congress & the American Geographical Society Library  have complete sets of published print charts {U.S & many International}. OSUL has a limited number of nautical charts. Please ask for assistance to see them.
