TEPaul,
Agreed as a source of information on Emmet's features, Kay has worked on a lot of Emmet's courses and should be a good source of knoweledge. Unfortunately, the finished products on some of those courses whether it be him or the membership, I do not know, is far from Emmet's features.
Adam,
Daniel Wexler's book Lost Links has some great pictures (that are from an American Golfer article) of Rockwood Hall (know NLE). These pictures show several green sites with original features. There are also some good pictures of Huntington Crescent Club's NLE course in the book as well.
