The Metropolitan Museum of Art has contributed approximately 5,500 images of European art and architecture photographed by William Keighley to the Artstor Digital Library.

The selection includes art and architecture from key cities in France, Germany, Spain, and Austria. Of particular note is a set of approximately 1,000 images documenting the pilgrimage routes to Santiago de Compostela in northwestern Spain. The shrine of St. James the Greater, patron saint of Spain, in Santiago de Compostela was one of the most important religious destinations for pilgrims during the Middle Ages. Currently housed at The Index of Medieval Art, Princeton University the complete collection created by William Keighley (1889-1984), consists of approximately 40,000 color slides, divided into thematic sets (the collection was formerly the property of the Metropolitan Museum of Art). It also includes Keighley’s notes, lectures and bibioligraphic holdings. Beginning in 1955, Keighley began to donate his slide collection to the Metropolitan Museum of Art to educate the public about the unique art and architectural heritage of select areas of the world. Keighley took up his research in art after his retirement from the entertainment industry in 1953.  Prior to that he achieved great success as a movie director for Warner Brothers, where he was responsible for many well-known films, including Bullets or Ballots (1936), The Adventures of Robin Hood (1938), and The Man Who Came to Dinner (1942).
