(FILES) In this file photo taken on August 18, Tiger Woods finishes the 18th green during the final round of the BMW Championship at Medinah Country Club No. 3 in Medinah, Illinois.    Woods is writing a book, called "Back", which he describes as his definitive story and says will clear up a lot of the "errors" and misinformation about his hall of fame golf career. "I've been in the spotlight for a long time, and because of that, there have been books and articles and TV shows about me, most filled with errors, speculative and wrong," Woods said. "This book is my definitive story. It's in my words and expresses my thoughts. It describes how I feel and what's happened in my life." / AFP / GETTY IMAGES NORTH AMERICA / Andrew Redington
