AMMDI is an open-notebook hypertext writing experiment, authored by Mike Travers aka mtraven. It's a work in progress and some parts are more polished than others. Comments welcome! More.
book by Dan Friedman and some other guy. Looks perfect for me, I always want everything wrapped in parens. I sort of know the basic stuff already but doing it with high-order functions sounds like fun.
The "Little" books have a kind of dopey q-and-a format (reminds of the worse aspects of PLATO) but it kind of works.
