No, but my understanding is that the historical claims are baseless, and that the book is pretty much worthless.
Ok, thanks to everyone that responded...as a Catholic, I've never read "Di Vinci Code," and don't normally make a point to read anti-Catholic literature. Still, "Angels & Demons" to my knowledge, is fairly accurate about its representation of papal elections. I wasn't endorsing its counterpart, "Di Vinci Code," nor do I present that as a case for any other consideration.
