If you’ve been following Twitter or the blogs, you’ll know that this has been Open Access Week. It’s been great to see many new open-access policies announced this week [Ireland, Belgium, Hungary], to read important explanations of why fully open (CC BY) OA is the way to go, and to see discussions from people like clinicians and librarians. It all contributes to the glorious sense that the transition to OA is beyond the tipping point.
