Daisy is a format for for providing access for folks with reading problems (keys available from the Library of Congress.) So here we have a case where the this out of print book is available to challenged folks but not to the rest of us.  Particularly ironic since it is a biography of the man who invented FM radio.

The author is a science writer, not the (much better known) lawyer, open source and free speech advocate.
Notes: Bibliography: p. 271-272.
