The dawn of Open Source Books
Everybody is talking about Wikipedia, the free encyclopedia that anyone can read and edit, an immense patrimony of free and open knowledge.
Another project from the WikiMedia foundation, less mature but very interesting, is WikiBooks, an archive and collection of free books, written, editables and improvables by users. The bigger part of WikiBooks is, of course, the english one.
A book that I find really interesting and that I want to suggest as an ”invite to reading“ on WikiBooks is “Lucid Dreaming“: a manual of techniques to learn to dream in “lucide” way, dreaming and knowing that we’re sleeping.
