USGS historical map collection now online

 RESTON, VA — Nearly 90,000 high-resolution scans of the more than 200,000 historical U.S. Geological Survey (USGS) topographic maps, some dating as far back as 1884, are now available online. The Historical Topographic Map Collection includes published U.S. maps of all scales and editions, and are offered as a georeferenced digital download or as a scanned print from the USGS Store.

"I applaud your continuing effort to digitize the entire set of USGS quadrangle maps and we anxiously await the completion of the project. This effort is of great consequence for the research community" said John R. Hébert, Ph.D., chief, Geography and Map Division, Library of Congress. Not all of the historical collection resides in any one location or in any one catalog. In a partnership with the Library of Congress and other map depositories, the USGS will build a complete master catalog and duplicate maps that may be missing from any of those sources.

Historical maps are an important national resource as they provide the long-term record and documentation of the natural, physical, and cultural landscape. The history documented by this collection and the analysis of distribution and spatial patterns is invaluable throughout the sciences and non-science disciplines. Genealogists, historians, anthropologists, archeologists, and others use this collection for research as well as for a framework on which a myriad of information can be presented in relation to the landscape. For more than 130 years, the USGS topographic mapping program has accurately portrayed the complex geography of our nation through maps using the lithographic printing process. The historical collection contains high-resolution scanned images from the USGS legacy series and other sources.

Historical maps are available to the public at no cost in GeoPDF format or as a printed copy for $15 plus a $5 handling charge from the USGS Store. The electronic maps are georeferenced and can be used in conjunction with the new USGS digital topographic map, the US Topo.

The entire historical collection is being loaded into the USGS Store at a rapid pace. Check the website for continuous updates: https://nationalmap.gov/historical.
