The discovery of Kryptonite, or at least a new mineral matching the chemistry described in Superman Returns, was found earlier this year. As a feral librarian (a librarian who hasn’t attended library school) I haven’t had a cataloging course, so I’m curious as to how articles on the new mineral will be cataloged for both its scientific and humanistic uses. Articles on a regular new mineral would just need to be listed via scientific categories, or so I’d think. But the hierarchical nature of subject headings would seem strange–at least to me–if the full scientific and full literary/popular culture hierarchy were included in the same manner. However, the popular culture study might intersect with the scientific so it could also be beneficial to list both on even footing.
