[Classweb-users] Works that prompted new classification number

[Mark Weiler]

According to https://classificationweb.net/approved/1801.html  several new classification numbers have been added. I'm interested in PN6231.S6325  and want to identify the work(s) that prompted its creation.

However, when I search by call number in the LOC catalog, there's no entry.  Does anyone have idea of how to find the titles or why no titles are present under that call number?
