MoreBeer has a
PDF catalog, but I don't think they've updated it in some time. It's also BIG - like 75 pages printed on both sides, IIRC - so that might be a concern if you want to print it for reading in the Chamber of Office.
I get Midwest, NB, and Williams via USPS.
Thankfully, I have a great wireless network and a laptop. I can shop while using the, er, Chamber of Office!
