I have a few personal diary entries from men in the 40th as well as those of the 37th on my website that's devoted to the 37th Alabama <http://www.alabama37th.com>. The site is organized in a chronological order and I wrote its entire contents in more of a "present tense" style so it might feel more like a day-by-day "diary" (although, it is admittedly a compilation of lots of information). If the information I've collected can provide you with assistance, I hope you'll use it. If this is for a grade, I trust that you'll follow all the proper source citations required for your class.
Good luck.
