I am no longer maintaining Catholic Resources on the Net (see the front page for more details) but I'm happy to report that the National Conference of Catholic Bishops is now maintaining a list of both Sunday and daily readings. They're using the New American Bible, the translation that's used in most US parishes. They're also including the Responsorial Psalm, which this page did not include.
You can find their page at http://www.nccbuscc.org/nab/. I highly recommend updating your bookmarks appropriately.
