The present volume gathers together the talks presented at the colloquim "Future Professional Communication II (FPCA-II)," held at the Harvard-Smithsonian Center for Astrophysics (Cambridge, MA) on 13-14 April 2010. Motivated by a convergence of facts and trends in the world of publishing, as well as by interrogations from within the astronomy community, the FPCA meetings are quietly making history as they are convening all major partners, publishers, editors, archive managers, officers of learned societies, as well as scientists involved in professional communication processes. The contributions presented in this volume describe their activities, projects and questions on the future.
