SlashDotDotDot's Journal: Follow up to "Mathematics Reading List"

A recently posted Ask Slashdot: Mathematics Reading List For High School Students? generated a long discussion filled with good (and bad) suggestions. It took a lot of work to read the discussion, so I though it would be useful to make a cheat sheet. Below are all the books--according to my own unscientific survey--that were recommended by at least two people, sorted by the number of recommendations. I probably missed a few as there were dozens of single mentions.

Hofstadter, Douglas R.
Godel, Escher, Bach: An Eternal Golden Braid

Abbott, Edwin A.
Flatland
Two other books were mentioned as good follow-ups to this book: "Flatterland: Like Flatland, Only More So" by Ian Stewart and "Sphereland: A Fantasy About Curved Spaces and an Expanding Universe" by Dionys Burger, Isaac Asimov, and Cornelie J. Rheinbold. "Flatland" also generated some discussion about whether the author was a sexist and whether it would matter if he were. Someone suggested reading "The Annotated Flatland: A Romance of Many Dimensions" by Ian Stewart to dispel the misconception.

This book doesn't meet my criteria, since it was only mentioned once, but since I was the mention-er, it earns a special dispensation.
