The upcoming authorized biography of Apple CEO Steve Jobs won't be out until next March, but it's already a best seller on Amazon thanks to a flurry of preorders.

"iSteve: The Book of Jobs" has been in the top 15 among the 100 best-selling books on Amazon for the past two days. Even further, the book has been the No. 1 best seller in three different categories: Business Professional's Biographies, Technology, and Biography & History.

Due to be released on March 6, 2012, the 448-page book will sell from Amazon as a hardcover version for $16.50 and as a Kindle edition for $14.99.

Author Walter Isaacson has been working on the book for Simon & Schuster since 2009, interviewing Jobs himself as well as family members and colleagues. The book promises to look at both the personal and professional life of Apple's famous co-founder.

Though unauthorized bios have been written about Jobs over the years, this will mark the first authorized version in which the Apple CEO is offering his direct involvement and cooperation.
