Can you show me an example of a library or cataloging agency that uses the "level of subject" indicator value in the 650 field? (The first indicator, not the source indicator value.) I have literally never seen it in the wild, but maybe I've been looking in the wrong places. If your library or agency uses it, why? If you know the reason why you don't, why is that?

[Dewey Decimal Filter] Looking for information about the Dewey Decimal System and its history of revisions. In particular: When and why did Mormonism get moved from Dewey Decimal classification 290 (non-Christian religions) to 289 (other Christian denominations)? [more inside]
