How can I find original field notes made by USGS geologists and geographers?

The USGS Field Records Collection is an archive of unpublished field notes, maps, correspondence, manuscripts, analysis reports, and other data created or collected by USGS Geology Discipline scientists during field studies and other project work. The collection is located in the USGS Library in Denver, Colorado, and is available for on-premises examination during normal library hours. See the Denver Library home page for schedules and location information.

For notes made by USGS topographic map surveyors, contact the National Geospatial Technical Operations Center at

Some USGS records are available in the National Archives.
