<p>We have decided that we can no longer keep up with all the great AI content on the web.
So we are no longer maintaining this page. 



<p>If you found our old list useful, you are still free to use this page.
In addition, you are free to download any of the following:



<ul>
<li><a href="ai">Source list</a> of AI URLs and categories.
<li><a href="ai.htm">Source code</a> for this page.
<li><a href="yaptu.py">Preprocessor</a> and <a href="CSS.htm">style</a> to make this page.
</ul>

<h1>Content as it was in 2015 (Some Obsolete)</h1>

<strike>This page links to <B><<len(links)>></B> pages around the web with
information on Artificial Intelligence.  Links in <a
href="#best"><b>Bold*</b></a> followed by a star are especially useful
and interesting sites. Links with a + sign at the end have "tooltip"
information that will pop up if you put your mouse over the link for a
second or two. If you have new links to add, mail them to <a
href="mailto:peter@norvig.com">peter@norvig.com</a>.  We hope you can find
what you want in one of the following subtopics:</strike>
