The tide having now turned in favor of open access on many fronts, it may be time to look at how publishing platforms contribute to the quality of knowledge. The PKP team has a number of initiatives underway aimed at enhancing the intellectual quality of scholarly communication for the benefit of both public and academic readers. Team members are leading initiatives in bibliometrics, data archiving, text markup, mega-journals, PKP School, and scholarly editions. These represent, at one level, technical enhancements and extensions of the newly integrated PKP platform. This talk, however, will focus on the potential contribution of each of these initiatives to the quality of knowledge, and thus will look to what follows from open access as a matter of the public and scholarly quality of knowledge that constitutes our contribution to democratic life.
