The Library of Congress Prints & Photographs Division has more than 76,000 images depicting World War I. The pictures include a variety of formats, including photographic prints and negatives, cartoons, posters, drawings and ephemera. The images are scattered throughout the collections, so understanding the collection strengths as well as best places to search will help you focus your research on the most likely sources of relevant pictures.

Most of the material was created during the war (1914-1918), but a portion deals with post-war topics such as injured veterans, pension distribution, and the aftermath in European cities.

The Library of Congress acquired the materials through copyright deposit, gift, and purchase. In some cases, other Library of Congress units, particularly the Manuscript Division, transferred visual material to P&P for care and service.
