Where do you see it referenced? That’s a valid sort of link, but I don’t think that’s an LCCN we have in the system. For example, here’s an XML record for the marc record of sn85042303:
But I didn’t find the LCCN 2016226265 in ChronAm.
I do see http://chroniclingamerica.loc.gov/lccn/2016226265/marc.xml referenced but if I go to it in a browser I get a page saying the requested resource could not be found. Has that moved?
