Take for example this newer document: https://archive.org/details/manualzilla-id-5695071 The document has horrible name and useless tags, and the content seems to be only section 2 of some SW manual. How would I ever hope to find it if I needed that exact document?
Obviously such huge archive cannot be categorized and annotated by small team, so it would make sense to crowdsource the labeling process. Yet, as registered user I can only flag the item, or write a review. Why doesn't IA let users label content and build their own curated collections of items?
