The 2009 American Crossword Puzzle Tournament is over, but you can still register and play online.
Blogs: Diary of a Crossword Fiend, Rex Parker Does the NYT Crossword Puzzle, Wordplay, NYT Xword in Gothic.
Software: Download the free Across
Lite software to view, solve, and print .puz files on Windows,
Mac OS, or Linux.
Macintosh users should consider Black Ink.
Acknowledgments: I owe this all to Will Johnston, whose Puzzle Pointers page I have shamelessly cribbed.
