Construct the URL as if it were provided by The Monastery. For example, suppose you wish to refer to Llama3 from another web site, define your A HREF as follows:
Here's an excellent book for <a href="http://www1.fatbrain.com/asp/BookInfo/BookInfo.asp?theisbn=0596001320&from=MDZ411">Learning Perl.</a>
The &from=MDZ411 parameter is what tells FatBrain that The Monastery is the referring associate.
P.S. Random HTML trivia regarding your .sig: Netscape 4x doesn't understand the — entity; however it does support the character code version, e.g. —. If you're interested in the support found in older browsers for other entities, this seems to be a reasonably complete reference. It is a little out of date, though.

Thanks. I did a isbn: link in the CB to generate the URL I needed. But knowing the rule makes it easier next time!
Re netscape 4: The complete list of entities has been published for years. How hard can it be? Shouldn't that be a matter of updating a simple file? I seem to remember an old Netscape that didn't like “quotes” either, but I thought that was History.
Hmm, why not have the Monistary convert entitiy names to numeric form?
