Thanks to Neil Mullins (Skar) for directing me to this. Paul Cornell has some quite apposite things to say about the e-books market and piracy etc. Here's the first two of his nineteen bullet-points:
1: Publishers have always thought that when you buy a hardback, what you're paying more for is the chance to own it on the day of publication. Paperbacks are cheaper because they come out a year later. The reading public, on the other hand, always thought what they were paying more for was the extra physical mass and quality. (Actually, a hardback costs, one publisher told me, only from 50p to a couple of pounds more to make.) So obviously publishers think an e-book, out on the day of publication, should cost the same as a hardback. And obviously the reading public think it should cost less than a paperback. From this difference in perception stem all subsequent horrors.
2: British publishers are faced with an additional cost for e-books in the form of V.A.T., Valued Added Tax, currently set at 17.5% of the sale price going to the government, set to rise to 20% next year. This tax doesn't apply to printed books. I asked Ed Vaizey MP, the Parliamentary Under-Secretary of State for Culture, Communications and Creative Industries, if this was going to change, and was told there were no plans to alter the V.A.T. rate at the moment.
