The Cambridge Handbook of Social Enterprise Law, edited by Ben Means (South Carolina) and Joe Yockey (Iowa) is at the printers and should be ready for orders in early 2019. 

My fellow BLPB editor Joan Heminway and I both have chapters in the book, along with many others. 

The introduction is posted on SSRN, for those who are interested. Also, editor Ben Means has many talents, as he did the cover artwork below as well.
