Deletion of Catalog numbering systems for single records

Comment: The article has no third party sourcing (99% of it is sourced from a single site, 78discography.com) and is just a bloated mess of trivia. None of this info would exist on the main articles, so why does a separate, exclusive one for this exist? It being a "valuable resource" should not be used as a defense when it fails other Wikipedia guidelines, which I believe is the case here. See
