The Haskell wikibook which includes the text from the great tutorial Yet Another Haskell Tutorial.
(The "Generic Haskell User Guide" paper is a fine paper, but I think it is a particularly bad recommendation for a beginning Haskell programmer, as it is more of an academic paper presenting extensions to Haskell and basically a different language "Generic Haskell" (i.e. Haskell with an old version of Generics) instead of standard Haskell 98. If you were looking for dense reading about Haskell, start with the Haskell 98 report.)
