The Cathedral & the Bazaar
"The leading challenger to Microsoft's stranglehold on the computer industry is an operating system called Linux, the product of thousands of volunteer programmers who collaborate over the Internet. The software behind a majority of all the world's web sites doesn't come from a big company either, but from a loosely coordinated group of volunteer programmers called the Apache Group. The Internet itself, and much of its core software, was developed through a process of networked collaboration.". "The key to these successes is a movement that has come to be called open source, because it depends on the ability of programmers to freely share their program source code so that others can improve it. In 1997, Eric S. Raymond outlined the core principles of this movement in a manifesto called The Cathedral and the Bazaar, which was published and freely redistributed over the Internet."--BOOK JACKET.
