Gentlemen (and ladies),
I have donated the notorious Nafziger Collection of orders of battle to the U.S. Army's Combined Arms Research Library (CARL). It is online and free to the world. I'm afraid I do not have the URL and I understand that it is still in a "teething" process, but it is there.
You may be wondering why. There are several reasons. First, technology was killing me. The collection was in WordStar, a DOS-based program, and Windows XP and Vista would not allow me to print the documents, so I found myself having to maintain a Windows 98 machine (and a spare, just in case). Sooner or later, I would no longer be able to get to the data. Technological changes would lose it to me (and you).
Second, I'm 60. Sadly, I'm not going to live forever. I imagined, not unrealistically, that since my wife and kids know nothing about the collection, could care less about it, would see a Windows 98 machine and think "junk" and place the computer, its hard drive and all the collection on the curb for the garbage collector, that my death would result in the disappearance of something that meant a lot to me as a hobby and a labor of love. Soooo, when approached by a friend two to three years ago, I realized this was the best solution. Besides, there is some sweet irony about a Navy Captain having his stuff figure so prominently on a U.S. Army website. 
And, in some sense, maybe I will achieve a modicum of immortality, leaving a legacy that will haunt you all long after I've shed this mortal shell.
And with that, if any of you are silly enough to want to order something on the old website (which is still functional), I will take your money, but pretty soon I'm going to take it down and leave a link to the army's website.
Enjoy, make use of it, and consider it my gift to the wargaming community.
