Publishers are happy to have a bite
Macmillan have now ended their stand-off with Amazon, and come to an agreement over the terms of sale of their ebooks. When Macmillan initially demanded new terms, all their books became unavailable on Amazon.
Now, even Rupert Murdoch says that Amazon's terms "devalues books", and he looks like renegotiating HarperCollins terms.
The problem is Amazon's selling model, in which they act as a straightforward reseller. They can sell the ebooks at any price they choose, even lossleading on some if they want to. Apple, on the other hand, have taken a completely different model with US publishers, who are welcoming it with open arms. Apple will be buying ebooks from publishers at a price set by the publishers, with Apple effectively taking a commission.
There's still no indication that Apple has started negotiating with UK publishers, so when the first iPads ship to the UK at the end of March ebooks might not be available through iBooks. If not, however, it won't be trhough lack of enthusiasm on the part of publishers. This is one American trend I don't think we'll mind following.
