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.) Most 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.
Just interested in old photographs that documents US history during the period 1865 - 1940. Especially those depicting industrial scenes and everyday life.
I'm slowly scanning old family photographs and posting some on Flickr here: http://www.flickr.com/photos/joedbart/
