Gödel, Escher, Bach is definitely a good recommendation, at least it appears to be from my cursory research on it.

As to what sort of recommendations I am looking for, I've noticed that LW appears to have a few favorite philosophers (Dennett among them) and a few favorite topics (AI, bias, utilitarian perspective, etc.) which I might benefit from understanding better, nice as the articles are. Some recommendations of good books on some of LW's favorite topics would be a wonderful place to start.

Thanks much for your help.
