FAS Nuclear Notebook

The FAS Nuclear Notebook is co-authored by Hans M. Kristensen and Robert S. Norris and published bi-monthly in the Bulletin of the Atomic Scientists. Each issue provides a snapshot of a nuclear-armed country weapons programs or a global nuclear weapons matter. The FAS Nuclear Notebook is one of the most widely sourced reference materials worldwide for reliable information about the status of nuclear weapons, and it is the most visited section of the Bulletin of the Atomic Scientists web site. Because of their importance as a resource to an informed public debate about nuclear weapons, the FAS Nuclear Notebooks are freely available on the Internet.

The most recent FAS Nuclear Notebooks are listed below. Issues dating back to 1999 can be found here, while issues from 1998 and earlier are available at Google Books.
