New FIDE Rating List
It's an odd-numbered month, and that means that FIDE has released its latest official rating list. You can find their top 100 (or rather, 103, since there's a tie for the last spot) here, and on the right sidebar of that page you'll find links to other rating information. If you want to look up particular players, this is the link you want.
Two other links of possible interest: Mark Crowther of TWIC offers some comments about the list's winners and losers, compared to the January list, while 2700chess.com keeps you abreast of what's happening with 2700-rated players in between lists. In fact, it already has some interesting information: quite a few of the top players, including world #2 Levon Aronian, still have unrated games not taken into account in the new official list. In Aronian's case, he has three games (at least two from the Bundesliga) which have yet to be rated and which bring him about five points closer to Magnus Carlsen and the #1 spot.
