There are some more websites like Wikipedia. They are also wonderful. You might be aware of them but still I want to recall those websites and their features.
(1) Wikibooks
Here you will get all free books with good contents. As of now it has a catalog of about 2,463 books and counting. You can get an option to search the books subject wise. There are different subjects like computing, humanities, science, mathematics, social science, languages, engineering and miscellaneous. This Wikibooks project started in 2003 and now has become the largest free e-books website in the world.
(2) Wikispecies
This is a website where you can get detail information about all the plant and animal species in the world. As of now it contains about 327,807 articles and counting. You will also get detail information about the taxonomical classification of a particular species. It covers Animalia, Plantae, Fungi, Bacteria, Archaea, Protista and all other forms of life. I like this website because it has made a detail classification of species.
