This collection consists of a wide range of mineral resource related items. It includes detailed and summary reports, memoranda, correspondence, notes, maps, and other documents. The documents were produced by former staff working for theTennessee Geological Survey, United States Geological Survey, and Tennessee Valley Authority. As of 2015 nearly all of the items in the collection located in the Knoxville Field Office have been reviewed and scanned, and are included in the metadata records here. The documents are all available in digital format as Portable Document Format (PDF) files. High resolution tagged image format (tif) files are available for the large plates. Currently all of the original documents are stored at the Knoxville Field Office. Ongoing work involves completing the portion of the collection located in the survey's Central Office in Nashville.
