What’s An Editorial Letter?

John Gilstrap posted a copy of the letter of suggested changes for his book from his editor in The Kill Zone.  It’s a very interesting look at the behind the scenes aspect of publishing a book.   The part about the profanity reminded me of another writer who was in my critique group.  He’d written a young adult novel and had profanity it in.  The editor wanted him to remove the words because he would lose out on libraries buying his books, which is a lot sales.
