I ran a search, but it looks like it was mentioned but never took off.
I was just watching the movie again the other day, and thought about this book. As he was flipping through it, I realized that the prop book could be Amazon.com: Holy Blood, Holy Grail Illustrated Edition: The Secret History of *****, the Shocking Legacy of the Grail (9780385340014): Michael Baigent, Richard Leigh, Henry Lincoln: Books which covers a lot of the same subject matter and was used in researching the original novel.
Here's the basic image needed if someone wants to run with it.
Have fun!
