From the Website's About Section: "As implied within its title, Civil War Notebook is essentially a virtual notebook, archiving my research into the American Civil War. The primary focus of this blog is original source material from both the antebellum era and the Civil War from 1861-1865."

From the Website: "Inside you will find information related to the U.S. Civil War including Union and Confederate Regimental Histories, Union Corps Histories, Soldier’s Letters, Diaries, and a variety of other information including helpful links."
From the Website's About Us Section: "We attended our first Civil War Reenactment in 2004, and ever since have been searching for any information we could find on the battles, the soldiers, the civilians, their way of life, etc. We also began a search for our Civil War ancestors, and uncovered a wealth of information. We are sharing that information here with you!"

This website has information regarding a lot of the German heritage of the American Civil War. The site doesn't seem to be updated past 2011, but there is some useful information if you are researching a soldier with German roots.

A citation list of all Indiana Civil War Regimental Files, organized by unit. This site does not include scans, photos, or links to the files themselves.
The host website for this link is Stones River National Park Service.
From the Website: "Please note that the Civil War Soldiers and Sailors System contains just an index of the men who served in the Civil War with only rudimentary information from the service records (including name, rank and unit in which they served). The full service records are housed at the National Archives and Records Administration."
