big list - Older editions of which books were better than the new ones?

Hausdorff's book Mengenlehre in the first edition had an appendix, omitted in subsequent editions, on the Banach paradox. (Later made into the Banach-Tarski paradox by Tarski...) Someone once told me this was the best, most elementary, presentation of it -- I haven't compared different versions of the proof myself.
