Indiana University researchers have introduced Laboratree, a web-based solution to the complex problems of scientific collaboration. ...
In addition to professional social networking, collaborators can upload documents to Laboratree, where colleagues can view, download, edit, and manage research papers and data. Colleagues will have access to all versions of a document, tracking edits made, while an intuitive check-in, check-out system eliminates conflicting changes.
Laboratree implements the recently developed OpenSocial platform ... Using OpenSocial means software applications and tools by others can be plugged in to Laboratree, freely exchanged between social networks that have incorporated the new platform. ...
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.
