A controversial view of public libraries from author Terry Deary. But he reveals a rather interesting fact in the course of this Guardian interview. He says that if one of his books is borrowed he gets 6.2p via PLR, whereas if it is sold he gets 30p. Based on the current Amazon price of a typical Deary paperback that means he receives just less than 7% of the cover price. This is exactly one tenth of what Kindle authors can receive. Of course you might argue that conventional publishing and promotion is what has enabled Mr Deary to reach the point where 500,000 people want to borrow his books rather than buy them, and there aren’t many ebook-only authors yet with that level of interest in their efforts. But it does expose the vulnerability of the traditional business model of publishing in very stark terms. As the Amazon juggernaut rolls on, will people still prefer to borrow a dog-eared paper copy of that book from the library when they could read it cheaply on a shiny, new e-reader or tablet? And will authors like Mr Deary still be willing to accept such a low percentage of the revenue their books generate?
