We have a spiffy "Welcome Area" here on reenactor.Net. It will show you how to get around and do some of the things we've found need a little explaining... to visit our Welcome Area, go here: http://www.reenactor.net/new_area/welcome_message.html
General Civil War Studies
This page has books about the Civil War which are general in nature. Give it a look and we think you'll find some good stuff here!
If you don't see a book listed here that you feel we need to have for sale, then PLEASE recommend it to us so that we can add it here!
