What are some seminal writings about ecommerce/retail/online brand-building?

I realize that the ecommerce/retail/online brand-building trifecta encompasses a lot, but they are certainly intertwined. I am trying to compile a list of seminal resources related to the intersection of the three. So far, here are a few that come to mind: - E-commerce is a Bear (Adam Dunn) https://medium.com/@dunn/e-commerce-is-a-bear-d233f02d52a5 - Building Brands and Running Retail (Tristan Walker and Ron Johnson) http://a16z.com/2014/09/04/building-brands-and-running-retail-ron-johnson-and-tristan-walker-break-it-down/ - Andreessen predicts the death of traditional retail (pando.com) http://pando.com/2013/01/30/andreessen-predicts-the-death-of-traditional-retail-yes-absolute-death/ ..and of course - Delivering Happiness (Tony Hsieh) What other titles or resources come to mind?
