I picked up a used copy of Jeff Ullman's Elements of ML Programming a couple of months ago for less than five bucks. It strikes me as compact and readable in the K&R style, in that it doesn't get bogged down in the tedium of regurgitated technical details or over emphasis on syntax.
It probably helps that ML [Ullman uses SML/NJ] isn't much on ceremony to begin with. Yet somehow, I never feel like it needs more curly braces and semicolons.
