I have been pondering the e publishing market for a while, and one piece of advice that I have heard over and over is to not simply publish one book at a time. Apparently authors who have multiple books available enjoy a larger amount of success than authors who only have one book, mostly because readers buy more books from authors with other stories they can read compared to authors who only give them a limited amount at a time.
My question is, do the other books all need to be in the same series? I have several stories that I am partway through writing and revising, but none are actually in the same series. In fact, a lot of them seem to have trouble fitting into the same genre. Would that handicap my progress as an e published author if I put them up online at the same time, or would it be just as helpful? What do you guys think?
