Jürgen Hubert wants to read European Guilds by Joel Mokyr (Princeton economic history of the Western world)
I bought this book as a result of an Internet Argument where one of the posters claimed that the medieval European guilds were in their own way just as horrible as the large multinational companies of the present #LateStageCapitalism (though on a smaller scale) - and they cited this book as a reference.
If nothing else, this book should give me some useful context for my own #folklore research.
