A friend of mine recommends reading 3 calculus books to learn calculus. I generalize it to reading from 3 sources to learn anything. I also postulate a law: the 3rd source you read is the best.
And so, here is a bunch of sources for learning haskell that I have tried at least a bit and liked, and so I can recommend them (for what my opinion is worth). There is a link to more at the end.
Pick 3 from this list and/or other lists. And if you want to know which one is the best, answer: the 3rd one you read.
There is a larger list on HaskellWiki.
