Most of the photos on this site were extracted from reference images (high-resolution tiffs, 20 to 200 megabytes in size) from the Library of Congress research archive. (To query the database click here.) Many were digitized by LOC contractors using a Sinar studio back. They are adjusted by your webmaster for contrast and color in Photoshop before being downsized and turned into the jpegs you see here.
"Photos taken during noon hour, October 23rd, 1912, at the Loray Mills, Gastonia, N.C. They said they were working and went in to work. At night I counted over thirty children coming out when the whistle blew, and they seemed to be from ten to twelve years old. The Superintendent was much disturbed over the photos."
