After running a search, your results will be displayed in a Thumbnail mode, displaying a thumbnail with title, creator and date information in the caption. You can also display results in larger thumbnail mode, which displays additional information with larger thumbnail images, by clicking on the second icon located under the Advanced Search link in the center of the page.
Use the navigation arrows on the right to scroll through the images displayed in your search.
You can SORT your results, in either Thumbnail or List Mode, by Creator, Title, Date or Recently Added. Simply choose one of these options from the Sort menu on the top left of your results screen. The date refers to the creation date of the object, and the sort order is date ascending.
Clustering: Artstor clusters duplicate images. The image that is the first within the cluster, and hence connoted as the authoritative copy, is either a Museum contribution, or an image that is determined to be empirically better than other copies of that image residing within Artstor. To view all copies of an image, click on the icon (mousing over this icon, you will see the words: "View related media") below the image in your results list.
