As coal companies closed business in Indiana many times they deposited their records at the Indiana Geological Survey (IGS). The records in most cases were delivered in boxes or full filing cabinets without documentation. The IGS has preliminarily sorted through the records filing them by company and if possible county or Township-Range to make them discoverable. The records can contain anything from maps, analysis, logs with or without picks, descriptions, correspondence, etc.

The National Coal Resources Data System (NCRDS) began as a cooperative venture between the United States Geological Survey (USGS) and State geological agencies in 1975 and focused on the stratigraphy and chemistry of coal. The current component databases of NCRDS include: USTRAT: Stratigraphic data related to coal (e.g. drill holes, measured sections) USCHEM (COALQUAL): Ultimate, proximate, and USGS-generated major-, minor-, and trace-element data for coal samples collected by USGS and States. USCOAL: A historical database of coal resource estimates compiled from publications prior to 1978 The collections referenced here are for historical purposes. The most current and up-to-date coal information is available electronically...
The National Aeronautics and Space Administration (NASA) and the U.S. Department of the Interior through the U.S. Geological Survey (USGS) jointly managed the Landsat program beginning in the early 1970s. NASA built and launched the satellites and the USGS preserved and distributed an archive of more than three million Landsat images to people in over 180 nations and territories. A joint effort between the Department of Interior and NASA began, ultimately producing the Earth Resources Technology Satellite (ERTS) program. Perhaps the greatest contribution of Landsat is the ability to understand how the Earth's land surface is changing through time.
