Thanks, birdseed and wow. That pretty much explains the problem--and solution: terms of art.

Birdseed's use of the phrase 'annotated bibliography' sent me to onelook.com--and that sent me to a librarians' lexicon. Here's the definition:

"In a more general sense, any brief explanatory or descriptive comment added to a document, text, catalog entry, etc. In a critical annotation, the commentary is evaluative. Also refers to the process of annotating a document or an entry in a bibliography or catalog."

Thanks again. Live and learn, my motto.
