No more hard copy parts books

What do you do when you want to find a faucet part or identify a fixture when are in the field and there aren't any hard copy parts books anymore. I guess it's to go online with a laptop and a satellite connection or go by experience or just replace the whole fixture which could be cheaper in the long run. Seems like faucet makers are making a game of just trying to remove some handles or spouts by hiding any evidence of any screws to remove. They are even hiding the brand names and good luck guessing the model. It should all be stamped on the back by law. Any ideas or comments appreciated.

Thanks
