When searching for criticism on the Shorter library catalog, the most important thing to keep in mind is that you are searching for the artist as a subject because you want books written about the individual, rather than books written by him or her. When you pull up all the books about an individual, those which are most useful as critical sources will include "Criticism and Interpretation" as part of the subject heading.
Examples:
Faulkner, William, 1897-1962 -- Criticism and Interpretation
Shakespeare; A Critical Study of His Mind and Art
The Novels of Jane Austen: An Interpretation
