Okay, I want opinions, thoughts, gut feelings. If you intend your first novel to be the first in a series, would you identify it that way on the cover when you self-publish? That's assuming that Book Two, Book Three, and so on are only drafted/outlined/sorta-started/thunk up. That is, they exist only in your mind. Pros: It'd be a BIG incentive to get those follow-on novels done It could build reader anticipation for the next books in the series It'd make sure you designed the series tag into the cover from the word Go--- you wouldn't be messing up the composition crowding it in later It'd save you the hassle of working with CreateSpace, etc., to switch out the cover on the first in the series, once Book Two was ready It'd save you from having to waste one of your precious ISBNs on the altered cover of Book One Cons: It's possible that the mere addition of a tag on the cover won't turn the book into a separate edition. So it wouldn't require its own ISBN Calling a novel "Book One" implies that other books in the series exist. When they don't you'll frustrate readers who like your novel and can't find the other ones. What if you never get the subsequent book(s) done? You'll look like an ass and really piss off your readers. You won't like that. Unless, of course, you didn't write them because you died, in which case you won't care. I notice this forum is tagged for the self-publishing of print books. But this question applies to e-pubbed books as well. What do you think?
