Where do you get a Pantone book?
You could always buy them by the chips if you only need them temporary:
Another option would be to see if someone is selling them used (local sign shop/print shop). Some shops do believe that a rotation of 2 years is standard to purchase and stay up to date with Pantone Books. If you are only needing a few colors you could always consult a local FedEx/Kinkos and ask if they have a Pantone Book on hand to see some colors for some work you may want to get printed. I have seen some go for sale if you are not in a hurry from sign shops on Craigslist going out of business, too.
After realizing you are near me I remembered that there is a search option on Pantone to find a local dealer:
