As much as I like my many editions of the "World Atlas of Golf: The Greatest Courses and How They are Played" my latest buy from Amazon, page 192, shows the 13th green at Merion described as "The 219 yard 3rd, one of the game's great short par threes,".
It is still a wonderful "new edition", and I thank Mark Rowlinson for continued fine work.
It sellls for $15.98 by the way. The list price is $39.95.
