It is the University’s policy to establish a comprehensive database of research outputs, recording bibliographic information and, where permissible under publishers' copyright policies, providing access to the full text of published research produced by University staff and research students.
The University therefore requires that all staff and research students submit the following to the repository:
Full text electronic copies and bibliographic details of peer-reviewed research published from 1 January 2010.
Bibliographic details (including abstracts, where available) of peer-reviewed research published between 1 January 2001 and 31 December 2009.
and that:
The electronic version of theses accepted for research degrees after 10th July 2009 will be deposited in the repository on behalf of the students. ...
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.
