What do you consider "reputable" sources?

How about Encyclopaedia Britannica? Or academic history books written by scholars at legitimate universities? Heck, practically anything is a more reputable source of history than Dan Brown's novels, Holy Blood, Holy Grail and other pseudohistorical trash of their ilk.

If there is anyone who is deceptive in this whole thing, it's the Catholic Church convincing their followers that Brown's book is presented as fact.
