Looks like an updated version of his 1998 book "Introduction to Functional Programming using Haskell": http://www.amazon.com/Introduction-Functional-Programming-using-Haskell/dp/0134843460 http://www.amazon.com/Introduction-Functional-Programming-us... The 1998 book was excellent, except that it came just before Haskell 98 and so one or two examples needed a little modification before they would build with GHC, but really it was a paper and pencil type of thing. I read the whole thing sitting in a copyright library without a computer because the book was two expensive to buy and was not in my university library. Looks like that won't change with this update.
