Recently James Corbett did an episode of Corbett Report on tools for online researchers. He listed some he uses and then his site members listed more in the comments.

Here I've compiled them all together with a brief explanation. You can now find this list on the links page in it's own "Tools" section. Suggestions for additions to the list are welcome, here in the comments, or sent to modmail anytime.
