(Free) Free and Open Source Software Book
MIT press is offering the book Perspectives on Free and Open Source Software for free download. From the synopsis:
What is the status of the Free and Open Source Software (F/OSS) revolution? Has the creation of software that can be freely used, modified, and redistributed transformed industry and society, as some predicted, or is this transformation still a work in progress? Perspectives on Free and Open Source Software brings together leading analysts and researchers to address this question, examining specific aspects of F/OSS in a way that is both scientifically rigorous and highly relevant to real-life managerial and technical concerns.
I wouldn’t let it get in between you and the next Harry Potter release, but skimming through it it looks pretty good with a wide variety of topics, each topic covered by different authors. Plus, you can’t beat the price.
