The aim of this paper is to present the Centre Mersenne for Open Scientific Publishing, a new open access scien-tific publishing infrastructure for publications written in LaTeX.The Centre Mersenne was launched in January 2018 with the first volume of the newly-created journal Algebraic Combinatorics.This non-profit initiative hosted by French public institutions was created to address a growing need within the scientific community for alternative solutions simultaneously scalable, sus-tainable, trustworthy, of high quality and at fair price.The Centre Mersenne supports publica-tions such as journals, books and pro-ceedings from any scientific disci-pline, provided they are written in La-TeX and engaged towards Diamond open access.
