This is a set of thirteen OER case studies from around the world. The descriptions follow a common format, describing the opportunity, innovation, benefits, challenges and potential in turn. A contact person is provided for each. Some of the descriptions become fairly detailed. There's obviously some overlap with the OER world map (which has hundreds of projects listed) and in fact the text in both is the same (eg. Athabasca University in this document and in the OER world map, or this one and this one from Scottsdale Community College) - it would be useful to know which of these (if either) is the authoritative source where we see this overlap.
