I am on my fourteenth completed game and have got all the collectibles in all games except for a tablet piece, or two, in each and every game. I agree this can be hugely frustrating, it's one of the low points of the game IMHO. Apart from that I love it. Does anyone have a spoiler for how to get the tablet pieces quicker? I have found that if I click on the collectibles on the collectibles page when I don't get one for a while, one turns up shortly afterwards, (perhaps a coincidence) but not so with the elusive tablet pieces.
