So there's this article explaining what a private collection is and there's this sentence that confused me: "A private collection is a privately owned collection of works, usually a collection of art. If seen in a museum alongside a work or describing a work, it signifies that piece of art in a museum is not actually owned by that museum, but is on loan from an independent source, either for the long term or for temporary exhibition. what doesn't make sense to me is when they say "if seen in a museum alongside a work or describing a work." Assuming they're talking about a private collection of works, how can it describe a work? And I know they don't mean "alongside a work or a description of a work" because they use "describing" like it's a verb the subject (collection of works) is performing. So can someone please explain to me what this means?
