I'm sorry that I don't have a good index or personal awareness to share. Boyd's book linked in a peer response is a source but otherwise I can only offer that B-Corps [0] or Benefit Corps are the formally/legally recognized entry into space. A structure like the FairShares Common is a sophistication, based on the articles of incorporation above and beyond establishing legal obligations to a purpose (as is part of B-Corp incorporation). It is, itself, based on the FairShares [1] and Commons ideas [2].
