Thats right, they have released PDF files of the complete set of Nimitz's Gray Books. This has been on my reading list for a while now and am in the process of trying to find hard cover printed copies but am also thinking of just printing my own from these files. If anyone gets a chance to read it, let me know what you think. http://www.ibiblio.org/anrs/graybook.html
Thanks for such info, Canadian Commander! Definitely I'll go through the pages but it'll require time.
I have almost finished half of volume 1 but like you said it requires time. There is alot of cool info in there.
