From Chris Bourg:
The MIT Libraries’ vision is for a world where enduring, abundant, equitable, and meaningful access to information serves to empower and inspire humanity.
So my top priority is to get research outputs out from behind paywalls and off of proprietary infrastructure.
I hope the connection to learning is obvious, but will state my sense of that anyway – I want teachers and learners to always have access to credible, relevant, current research; without economic, social, or geographical barriers.
