I would also add <a href="http:&#x2F;&#x2F;mmds.org&#x2F;" rel="nofollow">http:&#x2F;&#x2F;mmds.org&#x2F;</a> in the list. Link to the book is &#x27;<a href="http:&#x2F;&#x2F;infolab.stanford.edu&#x2F;~ullman&#x2F;mmds&#x2F;book.pdf" rel="nofollow">http:&#x2F;&#x2F;infolab.stanford.edu&#x2F;~ullman&#x2F;mmds&#x2F;book.pdf</a>.
