where do you guys get your shop manuals?

I've been finding myself doing more than just car starters. Everything from installing inverters, USB jacks, even drilling the roof for antenna mounts and running coax. My question is.. where do you guys get your shop manuals? Sometimes I just can't figure out how to remove a trim piece, headliner, etc. I would prefer to have good info instead of breaking something! I've used AlldataDIY before but it doesn't cover a lot of newer vehicles... Any info would be appreciated. :)

I haven't found a single source that covers all info for all cars. Myself, experience plays a big role in knowing where to look for things in a car. If I can't figure it out, then it's usually google or youtube searches. Forums are also a great source of information. Pretty much every car has at least one forum dedicated to it at this point, and chances are someone on the forum has done what you're attempting.
