The following applet displays the numbers of copies of the PDF version downloaded by visitors to this web site each week so far since I started monitoring on 1 July 2001.
If you are using Microsoft Windows and a Security Warning box pops up saying that the application has been blocked from running because it is "untrusted" please click here. If you get similar messages with Linux, please click here.
I did not continue to monitor downloads after October 2002. Applet: source code.
