Apparently there has been some grousing that the free, downloadable version of Larry Lessig's new book, Free Culture is in a proprietary format, namely PDF. Larry responds to the criticism here: Free Culture Followups. He makes the obvious point that the book has been released in one of the most free of the Creative Commons licenses, attribution, non-commercial, which means that anyone can port the PDF to another format as long as they leave Larry's name on it and aren't selling it.

Well, someone has already taken advantage of the license. Blackmask, an excellent source of free, online books (I dig their pulp fiction collection - the genre, not the movie), has ported Free Culture into other formats.

Seven of them:

Ms-Reader † Acrobat † Rocket eBook † Zipped format † iSilo † Mobipocket † EasyRead
