[LibX] LibX with subscription WorldCat catalog?

Thanks for the information, Godmar. Converting the POST form to GET 
failed with a 404 error for me. I will see if any of the folks here who 
handle the OCLC subscription have any documentation that I can use.

Also FWIW, our link to WorldCat is 
http://firstsearch.oclc.org/fsip?dbname=WorldCat&done=referer, which is 
what led me to believe that our access was IP address-based (and 
therefore I could set it up as a custom catalog in LibX).
