I have the Bicycling Guide to Complete... and the Park Tool's Big Blue Book, too. Of the two I much prefer the BBB, mainly because it is so clear and straight forward and has pictures that really make sense for me.

I need very clear pics and simple instructions, because I have no clue in heck what I'm doing!

Also, if you need more in depth or a different approach, you can go to the Park Tool's website for more info on whatever you're trying to fix.
