Shared libraries follow the same entropy curve as shared drives: enthusiastic curation, then accumulation, then a state where nobody's sure what's in there, three tags mean the same thing, and the safest move is importing the video again just in case — which is how the mess funds its own growth.

The fix isn't discipline; it's visibility. A library you can actually see — what's in it, how it's tagged, where the duplicates cluster, which topics are over-collected and which are gaps — is a library the team keeps using instead of abandoning for a fresh start that will entropy identically.

library_list and library_search are the audit tools, and they're free — browsing costs nothing. List by tag and type to see the actual shape of the collection; search titles to find the duplicate imports and the near-duplicates; walk the tag landscape to find the three tags doing one tag's job.

The audit output drives the cleanup: a duplicate list, a tag-consolidation map, and — the valuable surprise — the gap list: topics the team assumes are covered and aren't. Twenty minutes quarterly keeps the library an asset; the alternative is the shared-drive death spiral, with import credits attached.
