Into the Great Wide of Open: a dated (2013) but still useful slideshare by Clint Lalonde

This slidedeck, created by Clint Lalonde for the 2013 Tourism Educators Conference, includes detailed slide notes in the bottom half of the page. Some of the information is rather dated; nevertheless, it does provide a good overview of the types of Open and hints at some of the ambiguities and issues in the field.
