In our consortial environment we are maintaining a public list of libraries. The patrons can see the library contact information there for each library in our network - https://libraries.swisscovery.help.

We would like to add a URL link to this list to specific pickup library where the user has to pickup the title mentioned in the On Hold Shelf Letter (code FulPlaceOnHoldShelfLetter).

Unfortunately, the pickup library code is not available in the letter XML. There are pickup library name (request/deliveryaddress) or combination of library name and circulation desk name (request/calculateddestination_name). But these are not suitable for URL linking.
