Here is a list of great resources ONLINE for researching word and phrase origins.
Oxford English Dictionary (OED) - this is my main source, butit costs about $25 a month for a subscription
The Online Etymology Dictionary is a great place to do an initial search on an origin. I find that they match many of my other sources, including the OED and a bunch of my books.
Wordorigins.org, by the author of a great book called Word Myths, this website has great stories on words as well as phrases.
The Word Detective, another great resource.
I'll keep adding more in a bit.
