Where do Open Library subject terms come from? Is there any correspondence with the Library of Congress Subject Headings or any other, so called, "controlled" terminology set?
It appears that multiple sources might have been added together because there are, for example, http://openlibrary.org/subjects/dove_(ship) http://openlibrary.org/subjects/dove_(sloop_:_lapworth) which both refer to the same concept. There are also things mixed in which aren't subjects at all, or at least aren't used as subjects, like "Accessible book" and "Protected DAISY." These appear to be format specifiers. Is there a way to trace subject headings back to their source? Are there any other types of relationships between subjects other than just "related" (ie co-citation), for example, "broader" or "narrower"? What's the difference between a "subject" and a "place" or "person"? Things often appear in two of the three categories e.g. subject & place, which makes me wonder if they're distinct lists (and why). I guess what I'm really asking for documentation describing how all this hangs together in the OL context. I looked at the FAQ and http://openlibrary.org/subjects without finding anything illuminating.
