The Open Library is like Wikipedia but just for ebooks. Users can join in and contribute their time and effort to build the directory. The software and documentation is open for everyone. " Whether you fix a typo, add a book, or write a widget, it is all welcome. "
To start using Open Library you need to head over to its main page and sign in for a free acount. Once logged in you can then browse ebooks by subject, author, or lists members have created. You can also contribute your own new information or corrections of the catalog. If you are an author and you have a book to add then go ahead and click on " Add A Book " button on top of the page and add your work.
Open Library is really a great resource of reading materials for both sudents and teachers. I do recommend it.
