+on [Amazon](http://www.amazon.com/Little-MLer-Matthias-Felleisen/dp/026256114X).
+This covers some of the same introductory ground as The Little Schemer, but
+this time in ML. It uses another dialect of ML (called SML), instead of OCaml, but there are only
+superficial syntactic differences between these languages. [Here's a translation
+manual between them](http://www.mpi-sws.org/~rossberg/sml-vs-ocaml.html).
