The Don Greene Papers document the career of the conservationist and outdoor adventurist in photographs, audio and video recordings, and documents. The "Big Green Book," a large scrapbook album in the archive that was created for the nomination of Greene for the George Washington Medal of Excellence, includes the many recognitions and awards Greene received during his life.

Processing of the collection is ongoing, including digitization and cataloging of numerous slide format photographs, and digitization of audio and video recordings.
