Can't figure out how to separate these books (or how they got combined to begin with)

Help? Looking at the individual authors' combine pages doesn't show a way to separate these books, at least for me.

Ugh. I forgot to look at what the secondary title was, and now I've forgotten it. Anyway the easiest way to separate them is to use the separate tool.
