Letters, Diaries, and Journals

Greetings all - I have mentioned this on Twitter once or twice, but I thought I would put the call out here as well. This fall, I will be teaching an advanced studies course for 11th and 12th graders on the Civil War and Reconstruction, which will last for the full academic year. This course will rely heavily on published first-hand accounts. So...I am seeking suggestions for any published (and easily available) collections of letters, journals, or diaries. I have some good ones lined up for the Civil War units - Elisha Hunt Rhodes, Kate Stone, Sam Watkins, Robert Gould Shaw, and others - but I am having a much harder time finding similar accounts of the Reconstruction period. I will most likely put together a reader (I have a great collection of first-hand documents) if no good collections are readily available - so all suggestions are welcome :) Thanks in advance!
