As far as I know after searching for an answer as to what book spent the most weeks on The New York Times bestseller list, the book that was on the list for 216 consecutive weeks is "Midnight in the Garden of Good and Evil" by John Berendt. I have never read the book, however, I plan to do so since it was on the bestseller list longer than any book to date. If you have read it, did you like it?
This information below came directly from Random House. I actually found the information about this book being the book being the #1 bestseller the longest on the list from The New York Times.
