Author Seth Godin‘s new book Stop Selling Dreams is not available in the iBookstore.

Why? According to Godin, the book was not approved because the bibliography contains links to books on Amazon.

In a blog post on PaidContent.org, he wrote: “We’re heading to a world where there are just a handful of influential bookstores (Amazon, Apple, Nook…) and one by one, the principles of open access are disappearing. Apple, apparently, won’t carry an ebook that contains a link to buy a hardcover book from Amazon.”

What do you think? eBookNewser has more context: “With Amazon removing IPG books from the Kindle Store, Barnes & Noble and Chapters Indigo not selling Amazon print titles in their stores, and now Apple not accepting a book with links to Amazon in the iBookstore, book retailers are beginning to fragment and make the experience more cumbersome for the consumer.”
