Leveraging ICT to equalize access to education is critical in a world with over four billion poor people who have little access to formal education. Mainstreaming OER as a public good throughout the developing world could make an enormous contribution. The Development Gateway Foundation has established an online OER portal--"http://topics.developmentgateway.org/openeducation"--that provides descriptions and links to a wide range of OER content. Powerful open source collaborative platforms enabling collective authorship of content that is continuously updated and refined by users offer a new and unprecedented opportunity to advance OER content creation, localization, and dissemination. Collaborative tools hold great potential for delivering impact through improved utilization of OER; however, Website clearinghouse functionality that aggregates and disseminates external links to OER online and via e-mail should not be set aside. Content localization is of particular importance, and local partners have the expertise to build local OER capacity and facilitate OER content audits and inventories. Working together has created an opportunity to greatly expand the OER core content library by facilitating collaborative, user generated content. The Development Gateway Foundation believes the work undertaken together can lead to the wide availability of OER throughout the developing world. (Contains 3 footnotes.)
