LUNA’s Browse Categories feature offers users a snap-shot of a collection. Instead of only searching for media using the simple keyword or advanced search, you can go to this Browse Categories page and see the exact values for each data field. These categories are divided into Who, What, When, and Where. From this page you can also search alphanumerically.

Values are listed in alphabetical order under each of the Who, What, When, Where categories. The number of results containing each value is represented within parentheses.
Navigate through the list of values using the right or left arrows, or by clicking on the page number, using the navigation buttons at the bottom of each Who, What, Where, When category box.
You can also search alphanumerically.
Click on a value to see the results in the Thumbnail View.
You can then continue to narrow your search adding or removing additional data values, using the Narrow Search option in the Thumbnail View.
