If you are interested in social network analysis and happen to speak German, you should get yourself the newly published “Schlüsselwerke der Netzwerkforschung”. It’s a massive book that contains many short summaries and evaluations of important social network related texts. Find more information at the book’s homepage. I contributed a chapter focusing on Burt (2005): Brokerage and Closure.
