For Haskell, Learn You a Haskell for a Great Good (mentioned in the link) is excellent! Free digital version and pretty easy to follow. After reading that book, I was able to re-create a clone of Doom in Haskell, occasionally following along with https://github.com/levex/haskell-doom.
And in the fall of 2013, O'Reilly plans to publish the Real World OCaml book
This book has been published and is definitely worth a look if you’re interested in OCaml.
