Editions need to be un-combined.

[Anie]

"The Outlaw Bible of American Poetry" and "The Outlaw Bible of American Essays" should not be combined; they are different anthologies in the same series, not different editions of the same book. I can't figure out how to uncombine them on the edit page.

[Melody]

I separated them.

[This Is Not The Michael You're Looking For]

Book combining/separating is done on the combine editions page not the edit page. There is a link on the right side of the screen where it lists other editions. You can also get to the same screen from the author page.
