If we're mentioning songbooks, I said it before and I'll say it again, Irwin Silber's "Songs of the Civil War" is hard to beat. A very complete listing along with history and parodies. I'm with Uncle Jacque, as a follower of 19th century music, the Civil War was a treasure trove of music and songs. It seems like hard times and conflict inspire the writers, song writers among them. Even up to this day.
