The Prints & Photographs Online Catalog (PPOC) provides access through group or item records to more than 50% of the Division's holdings, as well as to some images establish in other units of the Library of Congress. Most of the catalog records are accompanied by digital images--about one million digital images in all. Not every images displayed in this catalog are in the public domain. The Library offers broad public contact to these materials as a contribution to education and scholarship. It is the researcher's obligation to decide and satisfy copyright or other use restrictions when publishing or otherwise distributing materials found in the Library's collections. In some collections, only thumbnail images show to those searching outside the Library of Congress because of potential rights considerations. High resolution scans for more than 3,000 large prints (approx. 24" x 36" or larger) are now produced. Subject matter ranges from battle scenes and cityscapes to portraits, religious iconography, and technology, with cartoons, advertising, and political campaign objects among the diverse forms represented in these once widely distributed prints.
