There are now 3,472 clustered images in Artstor. These clusters comprise duplicates and details centered around lead images that are chosen for their high quality. For example, a search of Hieronymus Bosch’s “Garden of Earthly Delights” will preference a high quality lead image digitized from a large-format color transparency and on-click reveals a cluster of images including six duplicate images of the full triptych and 96 details. In general, Artstor clusters are limited to paintings, sculpture, and decorative arts. Included among the over 2,000 new clusters uploaded recently are the Metropolitan Museum of Art’s Images for Academic Publishing (IAP) images, and a selection of images from the Scala Archives, the Erich Lessing Culture and Fine Art Archives, and the Philadelphia Museum of Art.
