To search the library catalog for commentaries that are not in the Reference section - this means you can check them out - do a keyword search for the name of your Bible book and the word "commentary."
For example:
Jonah and commentary
This search retrieves several results, most of which are on the shelves in the B section.
Single book commentaries published by Abingdon are listed in the catalog by book title.
For more information about locating commentaries, please see the Biblical Commentaries page of the Religion Guide.
