The Bulletin's bimonthly Journal can be found in over 15,000 leading universities and institutions worldwide. It is published in partnership with the Routledge Taylor & Francis Group, one of the world’s leading publishers of scholarly journals, books, ebooks, and reference works. First published in November 1945 as a 6-page black and white bulletin, the magazine has twice received the National Magazine Award, and is widely regarded as an authoritative source that brings the best scientific and policy thinking to solving the globe's most challenging problems.

Current Issue, Volume 73 Issue 5: In the September/October issue, top experts look at the hybridized strategies of Russia, China, and Iran and, more generally, at the militarization of the Internet that seems to foreshadow a continued increase in global conflict just below the level of full war.
