Events throughout the Netherlands are being coordinated by the SURFfoundation and range from a variety of workshops and presentations to the launch of a new OA journal, a redesigned institutional repository, helping researchers upload their publications to an IR, and an award for the researcher with the most publications in the IR.
Project NECOBELAC (Network of Collaboration Between Europe and Latin America-Caribbean Countries) will host a workshop in Rome, connected via teleconference to its partners worldwide.
The open access movement:
Putting peer-reviewed scientific and scholarly literature
on the internet. Making it available free of charge and
free of most copyright and licensing restrictions.
Removing the barriers to serious research.
I recommend the OA tracking project (OATP) as the best way to stay on top of new OA developments. You can read the OATP feed on a blog-like web page or subscribe to it by RSS, email, or Twitter. You can also help build the feed by tagging new developments you encounter.
