By chance, I found this wonderful anthology (Best Loved American Folk Songs) in our library last night. A gift from my wife's parents. In a short Mudcat note, I won't try to offer a 'review' (there are better writers than I). If you're interested, lookup an essay by David McAllister in 'Ethnomusicology' (Sep 1962).

My brief comments here -

Music arrangements by Charles and Ruth Crawford Seeger (!).
This 'treasure' sits with American Fireside Collection (1952) and my
    Sing Out volume 1 books
It's a shame that every Internet query about books points to Amazon,
   eBay or Google books.
I'm a bit surprised that I don't find a Mudcat thread posted already.
