Add a Copyright Notice to Copied Text

<script type="text/javascript">
function addLink() {
 var body_element = document.getElementsByTagName('body')[0];
 var selection;
 selection = window.getSelection();
 var pagelink = "<br /><br /> Read more at: <a href='"+document.location.href+"'>"+document.location.href+"</a><br />Copyright &copy; c.bavota"; // change this if you want
 var copytext = selection + pagelink;
 var newdiv = document.createElement('div');
 newdiv.style.position='absolute';
 newdiv.style.left='-99999px';
 body_element.appendChild(newdiv);
 newdiv.innerHTML = copytext;
 selection.selectAllChildren(newdiv);
 window.setTimeout(function() {
  body_element.removeChild(newdiv);
 },0);
}
document.oncopy = addLink;
</script>

just add this between your page’s head tags, and change the copyright notice to whatever you want.
