MSP (Mathematical Sciences Publishers) is focused on developing software for publishing, and on assisting and creating top-level scientific-research publications. We publish about 20,000 research pages per year, and we strive to offer the highest quality at the lowest sustainable prices. We are a scholar-led nonprofit publisher. Without shareholders to pay or a society to fund, every dollar that MSP earns is kept invested in our mission: to serve the math community through high-quality publishing at low prices, and help others do the same. Every page we publish is a page controlled by the math community, not a large commercial interest.
