i just stumbled about some of them more by accident then by actually searching for them.
i don't need to finish the game with 100%, but some of the cooler veil action only becomes available after a number of tomes have been found, and i'm stuck with only a few.
Try this link from mahalo, they always write good walkthrough's
It's step by step with video and gives you all the locations for gold,intel and tomes
