Recently Leo @leohavemann and I were discussing on how was the best way to encourage academics to use OER and share their materials, how can we make them see at the impact that sharing content can have and after reviewing some very interesting models of data visualisation, we decided that the best way was to generate a map with a which contains the list taken from the directory of repositories of OER and some new more.
To access the Map of OER Repositories please go to http://bit.ly/18NaDuu
The University of Loja in Ecuador has developed an OER map we use as inspiration to showcase a large list of OCW and other initiatives http://serendipity.utpl.edu.ec/map/ so we thank Nelson @nopiedra for sharing his ideas with us. Also, we thank @gconole @fbocquet @Open_Education @alacre @polx @fatenas and @Andreas__Link for sharing repositories with us and for sharing the map around.
If you want us to tag another repository you can contact us by leaving a comment on the blog or in twitter to me @jatenas or Leo @leohavemann, just remember that we will only include repositories of OER, for institutional repositories of books, thesis and other documents you can contact the DOAR team as they are the experts.
Thoughts on Open Education 
Great!
The VCILT in Mauritius is there! 🙂
We have an OER Impact Map (under development) at http://chaos.open.ac.uk which may be of interest. I’ve added this map and the Serendipity map to our collection at http://chaos.open.ac.uk/resources/. Will you be making your map data available on an open licence? We could do some interesting mash-ups! Anyway, more about our project at http://oerresearchhub.org/. Feedback welcome or just say hi!
How about the Open Textbook Library at the University of Minnesota (http://open.umn.edu)?
We have an OER repository http://repositorioaberto.uab.pt/handle/10400.2/4664. How could we includ it in this map?
Hi Madalena, I’m not updating this list at this moment, but https://oerworldmap.org and http://www.openaccessmap.org can index your repository
Best
