The Commonwealth of Learning an organisation based in Canada focussing on learning within the Commonwealth, has just opened this LO repository of materials from across the commonwealth.
A number of online databases of learning content or Learning Object Repositories – have been created around the world including CAREO, MERLOT and EdNA. COL has worked with eduSource and CANARIE (a not-for-profit corporation for advanced Internet development supported by its members, project partners and the Canadian Government) to develop the necessary tools, standards and protocols. The partners invested more than CDN $8 million in this venture. The software produced by this consortium has been made available in COLs Learning Object Repository under a free open source software license.
From a quick glance, it looks interesting, though it only seems to be possible to search at the moment, I couldn’t find the browse option.
