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.
Vintage photos of:

March 1911. Biloxi, Mississippi. "View of the Gorenflo Canning Co., taken at 7 a.m. Many tiny workers here, some of whom began to arrive at the factory as early as 5 o'clock, an hour before they were allowed to begin work, and long before daylight on a damp foggy day. The whistle had blown and they came and stood around merely to hold their places. When the shrimp 'catch' has been good, they begin work early, but today it was not good so they were waiting for daylight. In this group I ascertained the ages of a few, as follows. One child of 6 years, one of 7, two of 8, one of 10 and there were many more." (Lewis Wickes Hine.) View full size.
