Many of us know and use Wikipedia to look up on anything. It is a great reference site under general category.
Do you know there are great many wiki sites on specific niches? I have compiled a big list and I will write about them one by one.
Today's wiki site is on books alone.
It deals with popular books, authors, awards and literature. Learn more about the books in various languages such as English, French and Spanish.
Find great works on children's books, rare and sparingly known recipes, on all academic subjects and more.
There are even half completed books for you to read and edit the content! I heard that the most searched for books are 'do-it-yourself' books and 'body piercing' art aka tattoo art.
The PDF books on self development are hot favorites for many people. Visit the site located at http://www.wikibooks.org/
