Wikipedia – The Missing Manual

Wikipedia: The Missing Manual is a 2008 book by John Broughton. It is a how-to guide that explains the process of contributing to the Wikipedia online encyclopedia.

"For anyone who is interested in becoming part of the noble experiment, this book is an excellent introduction," wrote reviewer Robert Slade. Wikipedia: The Missing Manual is part of O'Reilly Media's Missing Manual series, which was created by David Pogue, technology columnist for The New York Times and Scientific American.

On January 26, 2009, O'Reilly announced that the content of the book was being released under a free license compatible with Wikipedia and that it would be available for editing in the Help area of Wikipedia.

The book has a spin-off, Wikipedia Reader's Guide: The Missing Manual, consisting of Appendix B (slightly expanded) and Chapter 1 from the book.
