I recently found Operation Charm. It's a project to digitize and make available factory service manuals for basically all makes/models. You can view them on the web, or save them to a local file and look at them offline.
They're all indexed and have clickable links.

The web address is Operation CHARM - manuals for all

 

Yeah, it's pretty cool. Some of the manuals are incomplete and some have pages mixed up, but overall a great resource!
