To get an overview of the distribution of digital repositories over the world, visit the Repository 66 map mashup, a project started in 2007 by Stuart Lewis ([email protected]) at the University of Auckland.

Repository 66 is based on data provided by ROAR (Registry of Open Access Repositories) and OpenDOAR (Directory of Open Access Repositories). The data from these sites are overlayed onto Google maps.

2311 repositories on the map

Currently the map shows 2311 repositories spread over the world. You can search  by repository software and by date of foundation. By clicking on a marker, you receive the availabe information on the repository, like its URL, a short description and a growth graph.

How to get your repository on the map?

ROAR provides an OAI-PMH interface and OpenDOAR an API which Repository 66 uses to harvest their data.

To get your repository added to the map, make sure you register it on ROAR, http://roar.eprints.org/index.php?action=add

and preferably also on OpenDOAR, http://www.opendoar.org/suggest.php.
