It has always been a problem that the OCLC Policy Directory has not been fully updated. The next time you are in there looking up a library and you don’t see the address information that you need, try clicking on the World Cat Regsitry link at the bottom of the entry.
Two things might happen. You might come to the acutal library’s record, or you might end up at the main page of the registry. If you end up there, click on ADVANCED SEARCH and enter the OCLC code in the box. My guess is that the World Cat Registry will eventually replace the Policy Directory in the future.
