Found an interesting thing about wiki....
Wikipedia as a Printed Book
The English edition of Wikipedia Encyclopedia contains around 3 million articles as of now and if someone were to print the entire Wikipedia encyclopedia into a book, the size of that book would roughly be equivalent to 952 volumes http://en.wikipedia.org/wiki/Wikipedia:Size_in_volumes of the Encyclopedia Britannica.

This Wikipedia book has some 5,000 pages and it’s a compilation of 400+ featured articles http://en.wikipedia.org/wiki/Wikipedia:Featured_articles all picked from Wikipedia. And, as you can easily make out from the photographs, the book is huge - it’s about 1ft 7in. high which is like placing 4 iPod Touch devices on top of each other

The more interesting part is that, Rob Matthewshttp://www.rob-matthews.com/index.php?/project/wikipedia/, who came up with this idea of printing Wikipedia, also has plans to sell this book according to Telegraphhttp://www.telegraph.co.uk/news/newstopics/howaboutthat/5549589/Wikipedia-turned-into-book.html .
