When searching the Library Catalog for books about graphic novels and their authors and illustrators, keep in mind that catalog records are very brief representations of information.
For example, subject headings about graphic novels will look like:
Graphic novels -- History and criticism.
Comic books, strips, etc. -- History and criticism.
If you are looking for discussion about a particular author or illustrator, try searching the name as a subject heading, or combine the name in a keyword search with concepts terms such as "criticism" or "interpretation."
These databases access the journal literature for Art and Design.
