GREDOS (Gestión del REpositorio DOcumental de la Universidad de Salamanca) is the new IR at the University of Salamanca. The IR is divided into four sections:
Digital library: Historical documents and documents digitized at USAL
Scientific repository: Research conducted or published at USAL
Teaching repository: Educational resources produced at USAL
Institutional archive: Administrative and institutional documents of USAL
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.
