Footnote, an online document service, is offering free access to their Civil War collection through June, 2010. This includes Civil War pension records, subversion investigations, photographs, maps, and a section devoted to Abraham Lincoln. You can check it out at http://go.footnote.com/civilwar_records/.

I am really sad that I missed that opportunity. Footnote is such an excellent source for information. Although if you can stand to dig through official reports and the New York Times archives you can still find tons of valuable information.
