With magazine sales, there's the original idea and then there's spawn, the tweaked idea that finds a niche in other magazine markets. Can you do the same thing with children's books? I have a non-fiction manuscript with an educational publisher, but I have also written a separate fictional story using the information I gleaned from writing the non-fiction piece. Is it all right to shop it around too? I feel like I'm double-dipping...When you say "I feel like I'm double-dipping", do you mean:
"I read my contract and am concerned that the non-compete clause would make this course of action legally precarious and could cost me thousands of dollars when both publishers demand I return their advances"?
Or do you mean:
"I've made the educational publisher aware of the fictional manuscript I've written on the topic and of my intention of trying to sell it elsewhere, and they've given me their blessing (in writing). And when I submit it elsewhere, I'm making very clear to other publishers that I wrote a nonfiction book on the same subject for an educational publisher and am including all pertinent details about that book (isbn, price, pub date, publisher)"?
