Recommend a bike maintenance book

I just bought the Zinn one today, I'm well impressed from just flicking through.

Those who say Zinn, would you say it was better to buy the older version of the book due to the nature of the beasts we ride? It's ok Hippy, I know you'd just Google the answer ;-) so I'm just asking the others ;P

Flicking through it I would say get the newest one. The only difference I can see is that you obviously don't have any mechs/shifters and have to deal with chainline instead - Sheldon has that covered.
