Free Software Free Society: Selected Essays of Richard M. Stallman, 2nd Edition (signed copy)
This book collects the writing of Richard Stallman in a manner that will make its subtlety and power clear. The essays span a wide range, from copyright to the history of the free software movement. They include many arguments not well known, and among these, an especially insightful account of the changed circumstances that render copyright in the digital world suspect. They will serve as a resource for those who seek to understand the thought of this most powerful man--powerful in his ideas, his passion, and his integrity, even if powerless in every other way. They will inspire other who would take these ideas, and build upon them.
