A post on the University of California Open Access Project wiki about an upcoming webinar points out that a pilot of the new publication harvester is now live at three University of California campuses (UC Irvine, UCLA, and UC San Francisco).
The harvester project is part of the University of California Open Access Policy that was passed by the University of California’s Academic Senate in July 2013.
What is the Publication Harvester? (via UC OAP Wiki)
The automated harvesting system will closely monitor publication sources, including public and licensed publication indexes, for any new materials published by UC authors. The system will gather as much information about the publication as possible and will notify the author by email when any have been detected. Author approved publications will then be submitted to eScholarship, where they will be available to the public.
This wiki page has a a lot of details about the publication harvester including planning documents.
Early this year (March 2014) we learned that UK-based Symplectic was selected by U. of California to implement the system.
Digital Science, a division of Macmillan Publishing (also owner of Nature Publishing), made an investment in Symplectic during 2010.
