“In recognition of PKP and SciELO’s twentieth anniversary, the Public Knowledge Project (PKP) and SciELO Program are entering into an agreement to develop a Preprint Server system on the principles that have guided these two organizations over the last two decades.
These governing principles include recognizing the value of: (a) independent manuscript evaluation systems and related services that are open to the academic community on a global basis, (b) comprehensive workflows for scholarly publishing that include options for preprint and post-publication commentary; and (c) affordable open source software systems for the underlying infrastructure for scholarly communication.”
