+    (description
+     "In 2002, Sam Williams wrote Free as in Freedom, a biography of Richard
+M. Stallman.  In its epilogue, Williams expressed hope that choosing to
+distribute his book under the GNU Free Documentation License would enable and
+encourage others to share corrections and their own perspectives through
+modifications to his work.  Free as in Freedom (2.0) is Stallman's revision of
+the original biography.  While preserving Williams's viewpoint, it includes
+factual corrections and extensive new commentary by Stallman, as well as new
+prefaces by both authors written for the occasion.  It is a rare kind of
+biography, where the reader has the benefit of both the biographer's original
+words and the subject's response.")
