The only complete dataset of bird migration patterns in North America is trapped in a basement — and it's going to take the power of crowdsourcing to free it.
Stored on 6 million note cards stretching back to the 1880s, the records of migratory birds were created by a network of thousands of volunteers who recorded birds' comings and goings, then carefully shipped their observations to the government.
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.
