Always wondered about that, I spent a lot of time in Borders reading the Apress Ocaml and F# books (and bought the F# books). The Ocaml book is ... exceptional

The whole experience (which went on for something like 2 years!) was screwed up from beginning to end. My apologies to you or anyone who spent money on that book. It was published against my advice. Apress promised there'd be a heavy copy edit/rewrite before publication, but that never happened.

Jason Hickey's OCaml book (search for it - a PDF is floating around) is excellent.
