I don't know if this has been posted here or not (feel free to delete if it has) but I just stumbled upon this:

Yeah, you have to be on the web to read it, but it's searchable for whatever you're looking for.

I can't believe I haven't seen this before.

only 1/4 or so of the book is there. it's a preview. still, it's a neat tool.
