FAS Nuclear Notebook

The FAS Nuclear Notebook is co-authored by Hans M. Kristensen, Matt Korda, and Eliana Johns, 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 website. Starting in 2020, the Bulletin only offers the Notebooks in web format, but full PDF formats are still available from Taylor & Francis. 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.

Older Nuclear Notebooks all the way back to the first issue in May 1987 can be found here (for those that are missing, see Google Books here). The FAS Nuclear Notebook is researched and produced by the analysts at the Federation of American Scientists. Previously it was produced by the Natural Resources Defense Council, headed by Robert S. Norris, and called the NRDC Nuclear Notebook.
