Mr. Johnson,
Thank you for your recommendations. I have been wanting to read the Noll book for some time, and will probably acquire it this week. I wasn't aware of the other two. Just to clarify, I'm not new to the study of American history, just to this topic apart from its social, cultural, and political impacts, which I've read about as it comes up in books on other topics. I have a couple of monographs and essays on specific aspects of the Second Great Awakening as well, but was looking for the best general overview--and your suggestions look great.
Eoghan,
I have read about Finney, and he certainly wasn't even the craziest of those who applied his philosophy of perfectionism to various reform schemes. Sylvester Graham was another minister/reformer of the period who did push vegetarianism to the point of inventing the flour for the Graham cracker, which you were supposed to eat instead of meat.
