One awkward thing about the supposed book stuffing “scam” is that it walks so closely to accepted industry practices. These compilations deceive readers by baiting them with promises of fresh content, like a new novella, at the end of a book which is otherwise all repackaged, previously published material. But mainstream authors do sometimes include bonus short stories or previews of upcoming titles in the back of a book — granted the book itself is usually original. The incentives that Kindle Unlimited generates to put out longer and longer books aren’t completely new, either — Charles Dickens’ verbose, meandering prose may reflect the fact that he was paid per installment. The 30-day Amazon Kindle cliff may necessitate ghostwriting, repetitive plots, and copycat writing, but none of these things are new in genre writing. Publishing and marketing have long gone hand in hand. Gaming the best-seller charts happens outside of ebooks — arguably, the major publishing houses live and die by their ability to game the best-seller lists.
