Two years ago LACMA made a relatively small number of its image holdings available for free download in an online library. From that beginning of 2,000 images, the museum recently expanded its downloadable collection by ten-fold, making 20,000 images of artwork available for free. This represents about a quarter of all the art represented on LACMA’s site. They’ve chosen images of artworks the museum believes to be in the public domain and developed a robust digital archive with a richer search function than most museums.
