Real World Haskell is pretty great. I much prefer to it Learn You A Haskell For Great Good!. They’re probably both going to be out-relevanced and perhaps out-done by Haskell Programming because it’s more current and it’s a very real attempt at making Haskell more accessible to people.
I’ve skimmed Clojure Programming and it manages to introduce people to Lisp very concisely and then immediately get into the strong points of Clojure in the following chapters in a very efficient manner. The first chapter is essentially “Here is what makes Lisp seem weird to a Java programmer” and then there’s an introduction to functional programming which I think will serve users of “normal” FP languages in presenting “Here’s how functional programming looks and works in Lisp packaging”.
Like I said, they then follow this up with getting into the meat of Clojure and how to use it to manipulate data, as the 3rd chapter is all about collections and the great generalizations they’ve made for them, how they all work and whatnot. At the end of that chapter is a sub-chapter called Putting Clojure’s Collections to Work which includes ending up with a pretty nice set of functions for a “Game of Life” board generation using Clojure’s nice FP bits and then also doing some GUI visualization of maze generation.
I think these first chapters will in general be enough for someone to get into Clojure and then the subsequent chapters are essentially "Here’s how to continue with abstractions of different types: Macros, protocols, etc..
All in all I think Clojure Programming seems like a pretty good book for learning Clojure and understanding why you’d want to make things with it.
