That's what the kind of book it came to my mind when I read the title. No, they differ though there is slight overlap and yes, someone should read them both. OfS first, OSC next. Specifically. OfS is an introductory OCaml book (first half) which has example usage of interest to scientists (second half). OSC though it has some introductory text per section is mostly concerned in showing Owl, which is what you'll end up using.
