Near-duplicate images

In this example, the image on the left provides more visual information. Notice the balcony seats on both sides that can be seen in this image, but not the cropped image on the right.  The cropped image, however, identifies the location and the photographer. In this case, we would scan and catalog the image on the right, note the existence of the image on the left, and use the identifying information in the catalog record.

For this image of Ute Indians by Nast, the Denver Public Library owns a glass negative and an original hand colored print.  We decided to catalog and scan the negative in greyscale. We decided that the hand-colored image was also of interest to researchers and cataloged and scanned it in color.
