Authored by Tim O’Reilly and Eric S. Raymond and published in 2001, 'The Cathedral & the Bazaar: Musings on Linux and Open Source by an Accidental Revolutionary' is a book that provides insights into new organizational structures emerging from the knowledge-based economy. It is cited as a key text for understanding firm types that are distinct from both traditional capitalist enterprises and worker-owned cooperatives, particularly in the context of open-source development.
