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.

This network of black magnetic beads, smaller than a postage stamp, is one of a number of input-output "memory" units in the new "704" electronic calculator built by International Business Machines. This particular "memory" unit of the 704 instantaneously strips all information off a slow-moving punch card, stores the data momentarily in the form of magnetic charges, and passes along the individual items, one at a time, to a lightning-fast calculating section, which can handle around 10 million operations an hour, theoretically replacing 3,000 hand-operated adding machines. Orders are in for over thirty 704's, which I.B.M. will rent at some $20,000 a month each. View full size. Photo by Ezra Stoller.
Autochrome portrait of a young woman thought to be Charlotte Spaulding, taken around 1908 by Edward Steichen. Made with a complex process using three hues of dyed potato starch, autochromes were glass positives viewed with a projector or mounted on a light box. Credit: George Eastman House Collection.
TWO EXAMPLES of early color photography by none other than Edward Steichen have come to light recently, the New York Times reports: "Almost as intriguing as the pictures themselves is the story of how they recently made their way from a house in Buffalo, where they apparently sat unseen for decades, to the collection of the George Eastman House in Rochester, one of the world’s leading photography museums, where they will be exhibited for the first time this fall."
