EPrints, ROAR and U. Southampton's Tim Brody and Les Carr have created a continuously updating dynamic map of recent OA Repository deposits worldwide, sampled minute by minute at:

The Registry of Open Access Repositories (ROAR) Global Overview of Open Access showcases open access material from repositories around the world. Picking one recent deposit at a time, the animated map cycles around the world's repositories showing a description of the deposit itself, together with a description and thumbnail of the repository's home page. Every few seconds another deposit is chosen from another repository, making what we hope is an interesting trip around the World of Open Access! The title of each repository and each deposit is linked from the display, allowing viewers to explore repositories and open access research from around the globe.
