Children and Youth in America: A Documentary History, Volume III, 1933-1973: Vol. 1 Parts 1-4; Vol. 2 Parts 5-7 (Children and Youth in America) written by Robert H. Bremner, John Barnard, Temara K. Hareven, and Robert M. Mennel was a great informative read.
As the title states, it chronicles the way that youth were perceived and treated during the years of 1933 through 1973. A bit too laden with correspondence, I think it is an OK source if you are researching the way that children were perceived during this time period in American, which is what I am doing for my upcoming book, Triple Threat: America's Misconceptions of a Misunderstood Society.
Though a good resource, I would not take it on vacation if you are in search of "light reading"
