Over the course of the last year, I purchased an International edition of Rudin's Principles of Mathematical Analysis (3rd edition) to supplement my undergraduate analysis course book. Going into the fall, it looks like a strong possibility that they'll be using this text for my first graduate level course in real analysis. While I know some international editions are exact copies of the original text, I'm also aware other editions are different (whether it be different problems, page numbers being changed, etc.). Does anyone have any experience with the international edition of this text and can vouch for its accuracy to the US version [either as a teacher or student]?
