The Office of the Deputy Assistant to the Secretary of Defense for Nuclear Matters — DATSD(NM) — has issued the 2011 edition of Nuclear Matters, which is significantly revised and expanded from the copy I have. (Here is a link to the 2008 edition.)
Nuclear Matters is probably the most useful reference book in my library on a day-to-day basis.
(I know, you are thinking “Assistant to the Secretary? Is that like Assistant to the Regional Manager?” Have I ever mentioned that I actually worked with someone who literally did that, albeit with slightly different titles?)
