History of the dockets

All DMA, DMEA, and OME files, covering the entire United States, and previously stored at Suitland, Maryland, were transferred to the Spokane office of the U. S. Geological Survey in 1993.  Also, DMA, DMEA, and OME files previously held at the USGS National Center at Reston, Virginia, and those formerly held at USGS field offices at Denver, Colorado, Menlo Park, California, and Knoxville, Tennessee, were transferred to Spokane. 

An unknown number of dockets previously held at U.S. Bureau of Mines field offices in California, Idaho, Montana, Nevada, Oregon and Washington were relocated to Denver, Colorado, where, upon termination of the U. S. Bureau of Mines in 1995, the files were placed in the Denver Records Center Archives.  Dockets formerly held by the U. S. Bureau of Mines, as were those formerly held at different USGS field offices, are essentially duplicates of the Suitland, MD files.   

Basic data from each file was entered into a computerized database that allowed ready identification and storage location of each file. In 2009 funding for data rescue was secured and the entire collection was scanned.

Docket scans

The entire collection of dockets was scanned utilizing Optical Character Recognition (when possible) and converted into Portable Document Format (.pdf) files which require Adobe Acrobat Reader for viewing. The file size of a scanned docket varies from less than 1MB to 500MB, based on the amount of information contained in the original docket and how many (if any) oversized maps are included in the scan.

Scan capture resolution ranges from 600-1200 dpi depending on original document quality. Oversized maps were scanned at higher resolutions. Original dockets are composed of vintage 1950-1970 era paper, carbon paper copies, mimeograph copies, linen, mylar, and other fragile and sometimes poor quality media. Overall most all documents are clear and legible. Scans include all docket material including hand written notes and oversized maps that may have been hand drawn and colored (not OCR captured).
