I'm still catching up on email from my internet outage and found that I received an announcement from the Center for Civil War Photography that the classic 10 volume work by Francis Trevelyan Miller, The Photographic History of the Civil War, is now available online. Click here to access the site. Quinnipiac University should be thanked for providing this valuable research tool.
While I much prefer the physical set it's not like you can carry it around with you so this should prove to be a popular site. I didn't stay too long at the site but I did seem to have trouble saving individual pages and photos. I was just doing it as a quick test and didn't put a lot of extra thought into it so perhaps I did something wrong.
Well worth checking out!
