I dont get to do them as often as I used to, but the only places I ever worked them regularly were Games Magaine (I always liked the World's Most Ornery Crossword Puzzle), and the Dell Magazine Family (I never succeeded in completing one of the Challenging ones, even with a lot of resource material). So you can tell I am not an expert by any means, especially not like those who can do them without resorting to reference material. I also like the New York Times, especially once Will Shorter from Games went there. Any of you out there recommend some great crossword material?

I'd especially be interested in any great 'How to' material.
