Not the sexiest site on our list, to be sure, but incredibly useful for gathering statistics and reports from more than 100 government agencies. Click on Key Statistic next to an agency's name (they're listed alphabetically) to pull up links to other Web pages containing relevant info. You'll have to dig a little, but for many kinds of research this is a great place to start.
First, a caveat. This is not a directory of the 50 greatest websites ever. Rather, it's a tally of the best sites launched or piqued our interest in some way since last year's list. Think of it as our round-up of 50 nifty links we think you should check out. So get clicking!
