Jean Ritchie's Celebration of Life: her songs...her poems was published by Geordie Music Publishing in 1971. It was distributed by Music Sales Corporation, which had some sort of connection with Oak Publications. It's still in print and available at Jean's Website. I don't know the name of the publisher of the current edition.
This book has many of the songs Jean wrote, along with a few songs written by Than Hall. Jean, who's Than? The book attributes most of the songs to Jean Ritchie, but I'm sure many of them are her versions of traditional songs.
