I don’t know if I am just unlucky, but every LCCN link that I have clicked on in an Edition page returns a message stating the LCCN entered can’t be found, e.g.: https://lccn.loc.gov/Q860831
I really don’t know what the Q number is all about. It is possible that the system was changed. The LCCN site uses a permalink url, e.g.: https://lccn.loc.gov/25015488
Maybe that is the link that should be entered as the ID.
