I've chosen the New Beginnings I feel are worthy of inclusion in Novel Deviations 3. Four of the opening authors declined to be included, but two had no objection to my editing their opening till it was unrecognizable as their work, so that I could use the continuation. One of them didn't like the continuation. The others are trying to sell their books, and seem to feel having 150 words of it published by EE would hurt their chances.
Allow me to ease the concerns any of you may have in this regard.
1. Virtually everyone who submits an opening is still trying to sell their work.
2. Excerpts from soon-to-be-published books appear in print all the time. Not just brief 150-word excerpts like you might see in a book review; also entire chapters. Chapter 1 of Harry Potter and the Goblet of Fire appeared in Newsweek. Apparently the publisher felt that this would help sales. They were right; it sold well. Short story anthologies consist mainly of stories that have previously been published in books and magazines. Not just brief excerpts, the entire stories!
3. I'll be printing 150 copies of Novel Deviations 3, and I expect to sell half that many, entirely to people who visit this blog. I doubt any publisher will be aware this obscure book exists. (Meanwhile, your opening sits on this blog which has had close to 800,000 visits. )
4. Chances are you changed your opening after getting feedback here anyway. Or should have.
5. No reason you can't use ND3 as a publication credit.
6. If your book does get published, and the opening appeared here, we will trumpet your success (as has happened several times), and readers of this blog may go out and buy your book. Your publisher will be pleased that you have done something to increase sales.
