Walter Isaacson’s Steve Jobs biography has been one of the most popular books of 2011. With the passing of the Apple CEO, sales of the book began to sky rocket and it appears Isaacson is planning to release a new version of his book.

From 9to5Mac:

Walter Isaacson cannot write an alternate ending for Steve Jobs in his famed biography, but the author is entertaining plans to expand the 630-page book in the future.

Isaacson shared his upcoming plans, and numerous anecdotes about the two years he spent with the late Apple CEO, at a Dec.14 event hosted by the Commonwealth Club of California. Fortune senior editor Adam Lashinsky moderated the sold-out discussion.

The biographer mentioned plans to create an annotated version of the best-selling biography.

In addition, Isaacson is planning on writing an addendum to the book that discusses the days before and after the death of Jobs.

“This is the first or second draft,” Isaacson told Lashinsky, while conversing about his book’s role in accurately documenting Jobs’ life. “It’s not the final draft.”

The book has become the best selling book on Amazon after being released only in late October.
