The Hewlett Foundation has announced that it is working with the Creative Common's ccLearn division to build a web search portal dedicated to open educational resources, with the assistance of Google. Organizations that sponsor repositories or collections of open educational materials are invited to submit information to CCLearn's OE Search project.
The initiative's goal is to build a comprehensive directory of open educational resources, encouraging their broader discovery and use.

The open access movement:
Putting peer-reviewed scientific and scholarly literature
