This interesting resource is a website, the Commons created by David Bollier, an American activist and blogger. Commons is not a fixed, universal thing but more a general concept describing durable, dynamic sets of social relationships for managing all sorts of resources: digital, urban, natural, indigenous, rural, cultural, scientific, etc., to use a few rudimentary categories. To enhance your studies, explore his unique Commons Course Syllabus: http://www.bollier.org/commons-resources/commons-course-syllabus
