I wish to learn Haskell.  I purchased a book – An Introduction to Functional Programming Systems Using Haskell but I think this might be too outdated.  I’m using GHC and it seems that some of the functions used in the book are no longer a part of Haskell.  I’m looking for advice on books or tutorials that might be more up to date.

So far I’m finding Haskell difficult – I may be too thick.
