Bestselling author Tim Ferriss will publish The 4-Hour Chef next week through Amazon Publishing and he will use the file-sharing site BitTorrent to promote the book. Through the partnership, BitTorrent members exclusive access to excerpts, unpublished writing and multimedia materials related to the book.

In 2010, Ferriss hit the Amazon bestseller list with The 4-Hour Body, a book traditionally published through Crown Archetype. A number of bookstores have said they will not stock his new book since it is published by Amazon. Here’s more from the site:

it’s poised to be the most banned book in US history. The 4-Hour Chef is one of the first titles underneath Amazon’s new publishing imprint; boycotted by U.S. booksellers, including Barnes & Noble. Disruptive voices should be heard. And traditional publishing’s probably about ready for a shakeup. So we’re partnering with Tim and readers like you to promote The 4-Hour Chef through BitTorrent. On the day the book launches, our community will get exclusive access to media from Tim: content from the book, as well as unpublished material. We’ll be distributing the writer’s process: the photos, drafts, videos and recipes that shaped Tim’s journey. And we’ll be asking users to support Tim and the Amazon imprint.

You also now have  a new Gallery view, which should be useful for showing off the photos, and the update also removes  the file size limit. You can now upload files of any size (bandwidth permitting). Read more
