Hi, I have 3 Haskell books, The Craft of Functional Programming (Thompson), Introduction to Functional Programming Using Haskell (Bird) and The Haskell School of Expression (Hudak). I recommend Thompson's book because it contains good explanations and lots of exercises, although the book is quite big and takes some time to work through. Bird's book is a bit shorter and is good for explanations too but it isn't quite so hands on as it contains fewer exercises. Hudak's I feel is a bit too advanced for a first read, it focusses on using the Hugs graphics library and I think that the graphics examples can sometimes cloud the simple ideas that are trying to be explained. I'll probably try reading it again in the future. All the best Dave O
