The Bulletin of the Belgian Mathematical Society - Simon Stevin (BBMS) is a peer-reviewed A1 journal devoted to recent developments in all areas in pure and applied mathematics. It is published as one yearly volume, containing 4-5 issues.

The main focus lies on high level original research papers. They should aim to a broader mathematical audience in the sense that a well-written introduction is attractive to mathematicians outside the circle of experts in the subject, bringing motivation, background information, history and philosophy.  The BBMS also publishes expository papers that bring the state of the art of a current mainstream topic in mathematics. The BBMS publishes papers in English, Dutch, French and German. All papers should have an abstract in English.

Since January 2003, the Bulletin of the Belgian Mathematical Society -- Simon Stevin is part of an aggregation of electronic journals under the name Project Euclid.
