I noticed there were some complaints about resources for Scheme. Here are some Scheme programming books divided into those looking to introduce computer science, and those interested in introducing Scheme. I've personally worked through ``The Little Schemer'' recently as a refresher and really enjoyed it, and I'm currently on chapter 14 of ``The Seasoned Schemer'' which is also very enjoyable. Hopefully some of you will find these useful if you're just beginning your journey.
