"An archivist has begun a massive project to make public a newly digitized collection of unique and sometimes startling military medical images, from the Civil War to Vietnam, without the Army's blessing.
This previously unreported archive at the National Museum of Health and Medicine in Washington, D.C., contains 500,000 scans of unique images so far, with another 225,000 set to be digitized this year."
