The Cathedral and the Bazaar

In this book, Eric S. Raymond discusses two distinct models of software development: the 'cathedral' model, where source code is restricted to a small group of developers, and the 'bazaar' model, where code is developed publicly over the internet.

Raymond draws from his experiences with the Linux kernel and his own project, fetchmail, to illustrate the benefits of the bazaar model, including the rapid discovery of bugs through public scrutiny.

The book also outlines 19 'lessons' for creating good open-source software and discusses the impact of this model on the broader software development community.
