Teri,
Unfortunately, professional writers are not in control of future values and it is a waste of time worrying about it. In other words, authors do not reap from sales of used books after the initial sale. We do well to get what we can from the publishing houses, which is about $2,000 per book, unless we have a good agent or a good track record in sales. Writers can't get rich unless they become Danielle Steele or Stephen King or John Grisham, et al. Self-publishing is an alternative to conventional publishing, and you can make all the profits on your book, but you also have to do all the work, i.e. publicity, etc. So all of that comes out of pocket, not to mention printing costs. My little book will cost $5000 to print 1,000 copies, so I was thinking of offering pre-orders of autographed copies at $50 each, hoping to sell the requisite 100 copies to cover the printing costs. This does not include the royalties I will have to pay to the cover artist or anyone else who feels I need to fork over cash. I suggest you join a local writer's critique group to learn the ropes about writing for profit and the ins and outs of publishing and self-publishing. I belong to a couple of groups myself and it's lots of fun besides being informative. In fact, I'm hosting a seminar on how to write historicals next month and will display my Titanic collection. Hope to take pictures to share. If I could just learn how to download them on the website!
