Hugo Riemann edition of Chopin Etudes (and other works)?

[virtuoso80]

I was recently browsing the book Chopin: The Man and his Music by James Huneker, and inside I came upon some examples from different editions of the Chopin Etudes, including many by someone named Dr. Hugo Riemann. The author illustrates for many of the Etudes and different and remarkable approach to phrasing and notation by Riemann, and I love it! Somehow, Riemann manages to spell out the minute details of rubato and phrasing that I had to find intuitively over time. I'd love to find a copy of his edition, and also look into what else he edited, but I can't find it anywhere!

Has anyone else heard of this edition, and do you know where I could find it? Also, for those who know, what do you think of this edition?

No one's got any info, huh? Do these editions even exist?
