title: where can I find a good boost reference?
body: <p>I'd like to have a good  up-to-date reference for boost by my side, and the only books I found are the following:</p>
  
  <ul>
  <li><a href="https://rads.stackoverflow.com/amzn/click/com/0321133544" rel="noreferrer" rel="nofollow noreferrer">Beyond the C++ Standard Library: An Introduction to Boost</a> </li>
  <li><a href="https://rads.stackoverflow.com/amzn/click/com/0321412990" rel="noreferrer" rel="nofollow noreferrer">The C++ Standard Library Extensions: A Tutorial and Reference</a> </li>
  </ul>
  
  <p>Both books are somewhat dated, and I am sure boost has been evolving.</p>
  
  <p>Obviously I can just use a direct source of <a href="http://www.boost.org/" rel="noreferrer">Boost website</a>. </p>
  
  <p>Is it enough to just use the website to learn and reference boost libraries? </p>
  
  <p>What If I am one of those folks who prefers hardcover books? Which one would you recommend?</p>
  
  <p>Thanks</p>
  
  <p><strong>--Edit--</strong></p>
  
  <p><em>Does anyone know of online  video tutorials on Boost, as well as text turials?</em></p>
