Thanks to this post by Eric Wittenberg, I’m aware that Microsoft has given up on its digitization project. A good many of the digital books I have listed on my First Bull Run Books and Articles On-Line page are part of this project. For now the links work, but if the project indeed “goes dark”, they’ll be worthless and I’ll have to find alternatives. As I do, I’ll change the hyperlinks. If you run across a link that doesn’t work, drop me a note. If you have an alternative site address, let me know that, too.
