_The Scheme Programming Language_ by Kent Dybvig is also very good. _Structure and Interpretation of Computer Programs_ is my preferred "how to think in Scheme" book. I would recommend against _How to Design Programs_, which is entirely too pandering and focused on imperative programming for my tastes.

For what it's worth, the second edition of How To Design Programs drops the imperative programming[1] and is available online[2].

I can't comment about the pandering though.

Is that just the first few chapters of the 2nd ed?

Many chapters after that one are just blank.

Yeah, I'm not sure. That's the "unstable" version, and it looks like some of the chapter's are missing (everything after part 6).

It seems there's a fourth edition:

Also, Wikipedia says that "Teach Yourself Scheme in Fixnum Days" is outdated in some parts:

TSPL4 covers RSR6 which didn't go over very well with the community. TSPL3 is probably the better bet there.
