I just bought the trilogy on origin the other day (the day before it went on sale) and i just cannot figure out how to look at the arts books that come with the digital copy of my game. Google hasn't helped at all either.

Find where you installed it. In my case it was program Files (x86) > Origin Games> mass effect 2 > Bonus last but not least Documentary! :D
