the davinci code by dan brown
The Davinci Code by Dan Brown does not enter the New York Times Bestseller list until April 6, 2003
Better choices are The Brethern By John Grisham for only during 2000 or Harry Potter and the Sorcerer's Stone which had entered the year before but was dropped in August with the creation of the Children's Best Seller List. This can be fact checked at time.com.
I was using www.hawes.com to fact check this answer
When I typed in Da Vinci Code as a book, I found the article revealing when it entered the NYTimes list.
