If you have a blog please consider adding a playing card to your site:
You can use the following HTML:
<a href="http://code4lib.org/"> <img src="http://code4lib.org/cards/code4lib1.png" border="0" alt="code4lib" title="code4lib"/> </a>
Feel free to use the images directly from code4lib.org if you don't want to go through the effort of grabbing them. This will allow us to secretly discover your site by trawling our logs.
