What do you recommend as the best way to find out which editors edited which books? I want to select books with certain similarities to my stories, and then submit to those editors.It's not easy to find those answers. Editors stay in the background a great deal-- deliberately. So the best you can do at most houses is to submit to the imprint which published the books you admired.
Sometimes googling a title and the word "editor" will come up with something, but at most houses they don't put up web pages listing most of the books an editor has worked on. But some do.
