Q: What is the difference between *anonymous* and *unknown*?

A: According to CCO, p. 91, an anonymous creator is one whose hand is identified and whose oeuvre is established, but whose name is not know. If no identity can be attached to an unnamed creator, the creator is unknown. While Getty ULAN includes records for “unknown” artists with cultural designations (e.g. unknown Rhenish) but we prefer to use local records which allow for the designation of the creator's role. The culture can be specified in the *Culture* field. Anonymous creators are often given descriptive names, such as “Master of the Housebook,” for whom Getty ULAN has an authority record [refid 500002780].

Q: How do I catalog an image with multiple works in it?

A: You will have to decide if the image you are working with faithfully depicts the works, in which case the image must be cataloged as a surrogate for those works, OR if the image is an artistic photograph that happens to feature other works of art. If you are cataloging the former, include creator and title information for:
1. Identifiable artists. (For more, see multiple creators in CCO, p. 85.)
2. Identifiable works

For a complex work, like Calder's Circus, include multiple titles and use view description to describe their arrangement in the image.
Here are some examples provided by the VRA, which may help to guide your decision-making:

Example 30: Multiple works shown in same image

Example 31: Related works shown in the same image

Example 135: Group of arrowheads
