A show that I was watching on The Discovery Science Channel mentioned a book that I had read a little of in high school and I remember liking, Flatland: A Romance of Many Dimensions. I searched Amazon for it and found a “Dover Thrift Edition” of the book for $1.50.
Curious to if there were any other cheaps books I would like, I searched for “Dover Thrift Editions” The search yealded 418 books, most of which are between $1 and $3.50!
Most of the books are of the sort that you read (or were supposed to read) in high school, and the only reason they’re so cheap is because they’re past their copyright period. Still, I think I’m going to get myself a copy of a few of them because for just a couple dollars, you can’t go wrong.
