Scribd.com is a site where one can upload documents, books, papers that one has written or has copyright privileges to. It supports many formats (PDF included) and even allows you to download a piece of work if you are allowed to by the original author who uploaded the document/book. For documents that are copyrighted, you can read the book/document right from the browser window itself.
I found this world-famous Maran Illustrated Yoga ebook that can be read at Scribd’s site.
Here are the links to some chapters. Other chapters are not available at the site.
I have browsed the ebook’s chapters and found it very helpful and informative regardless of the yoga level you are in (beginner or avid yogi/yogini). Hope you find it as interesting as I did!
