Just a few comments, as I saw this book has 5 stars:
Several things have been changed, compared to the original
edition, and although one may find them minor, I believe them
to be significant. The translation of Kodokans motto par example:
The vital part is "conveniently forgotten", and many formulations
bear the same mark; strength is over-emphasized, technique close
to being ignored. So, 5 stars to First Edition, and minus 2 stars
for leaving out the hall-marks of Judo in this newer edition.
Fortunately, winds seem to change in Kodokan now, so maybe a
third, "un-revised", edition is on its way?
