How can you find out who edited a book? Who edited the novel "Special Topics in Calamity Physics"?

I wrote it as a Google topic. None of the hits I got seemed from the synopses like they'd give an answer. It would take a while to read the hits in full and it might still be a while before I found an answer, if ever. This might be fun sometimes, but it would be nice if there was a quick way to find out who edited a given book. I suppose some authors may not have an editor, or teams of editors may work on some books.

The particular novel was published by Viking Press which I think is a big press so probably there was an editor?
