Through Didier, I got to Victor Shoup’s Home Page. He has an on-line textbook called A Computational Introduction to Number Theory and Algebra. It is unclear whether he intends the textbook to remain free, but it is pretty cool to post the book on his home page. Shoup’s is an expert in cryptography.

Daniel Lemire, "Victor Shoup’s A Computational Introduction to Number Theory and Algebra," in *Daniel Lemire's blog*, October 2, 2004.
