In 2009, Elinor Ostrom received the Nobel Prize in Economics for her “analysis of economic governance, especially the commons”. Since then I've seen a number of different versions of her list of the 8 principles for effectively managing against the tragedy of the commons. However, I've found her original words — as well as many adaptions I've seen since — to be not very accessible. Also, since the original release of the list of 8 principles there has been some research resulting in updates and clarifications to her original list.
