WikiSource is like a big library of books and other texts which are available for everyone to read for free. It's a place where people can share books and other written works, both old and new. They come from all different backgrounds, cultures, and languages - so you can find a really huge variety of texts here. You can also check out books you wouldn't find easily elsewhere, or find the original versions of books which have been changed or updated over time. When you're done reading, you can save and share the pages you find here with your friends.
