The Apple bookstore shelves are groaning under the extra weight. One of the world's largest publishers, Random House, has joined the iBooks store.
Almost as soon as the ink had dried on the contract, Random House added 17,000 of its titles, including authors Dan Brown and Stieg Larsson.
At the moment, it's only in the US store, but it's expected other Harper Collins' divisions, including the UK, will follow.
It's been a big gaping hole in the bookstore since iBooks was launched last year. And it's taken all this time for the publisher to agree to Apple's strict rules, which allow the publisher to set the cover price as long as Apple gets 30%.
Random House is already selling books on Apple's arch rival, Amazon Kindle.
It means Apple now has the world's six major publishers on board - Harper Collins, Hachette, Penguin, Macmillan, Simon & Schuster and now Random House.
