"It is all good fun, and the authors point out much that we readers would probably otherwise miss…. This annotated version of Flatland is clearly designed to be enjoyed by a very wide audience. … Readers of this edition will become more familiar with Edwin A. Abbott the person. The multitude of notes explaining, among other things, Abbott’s wordplay, his grasp of classical Greek culture, and his critical views of Victorian society makes us almost feel like we are having a conversation with him…. I highly recommend this edition. Abbott’s story can be enjoyed by those with a taste for any combination of mathematics, linguistics, social commentary, history, philosophy, religion, and faith. Lindgren and Banchoff’s notes and commentary deepen the enjoyment of these many dimensions of Abbott’s creation." David A. Huckaby, MAA Reviews
