The FOTD's are annotated quite nicely by Paul Lee with various web links. In the past there was a link to Paul Derbyshires "Quck Guide to the Mandelbrot Set" when describing various regions of the Mandelbrot set. The last known site where this guide posted seems to have gone 404. I been checking from time to time to see it might have found a new home. Then I found out about the Internet Wayback Machine at http://www.archive.org/web/web.php With it, you can find cached copies way back to 1996. A page might be cached several times. I was able to display the most recent cache of Paul Derbyshires Guide by going to this link.
