Since 1987, the Bulletin of the Atomic Scientists has published the Nuclear Notebook, an authoritative accounting of world nuclear arsenals compiled by top experts from the Federation of American Scientists. Today, it is prepared by Hans M. Kristensen and Robert S. Norris of FAS. The Nuclear Notebook is housed at [Taylor & Francis Online], home of our digital journal. Because of its importance to researchers, governments, and citizens around the world, the Nuclear Notebook is always free-to-access.
