I don't like to read fiction on the computer screen (having to do it all day every day for my own stuff, my eyes need a rest.) Nor would I read it as a serial (it would drive me crazy--not only interfering with my writing, but also tempting Demon Editor out of her hutch and thus requiring application of Moral Force to keep from writing the authors and saying "That sentence in chapter three, paragraph two, really belongs in chapter four paragraph eight...fix that in the next draft..." and similar maddening, unforgiveable intrusions. There is not enough Moral Force in my aging brain to manage this, and if I like the writers I want to stay friends with them.)

Thus I would contribute to such a project only if there were a paper (or printable) version and would want to make only one contribution.

Here it gets tricky. For a writer whose work I kindasorta like, but I really like the writer and want to support her/him, I might be OK with a PDF I could print, and my contribution would factor in the cost of the paper to print it. So that contribution would be less than if the book came already printed out. For a writer whose work I really like and want to keep around, it would have to promise the printed version...not a hardcover, but either a mass-market (for those I probably won't read more than a half dozen times) or trade PB (for those I know I'll read more than a half-dozen times.) Again, my contribution would be based on the estimated bookstore price of an equivalent...I know what prices are, and what the markup over expenses is, and would be prepared to gift the writer what bookstores usually yank, in addition to the royalty built in.

If I could stand to read a book off the screen, I'd want to pay less for just the download so I could read it whenever.

But that's just me, and I need to get back to work now.
