"Judaism--Controversial literature" is valid but how about "Jews--Controversial
literature"? and how about
"Karaites--Controversial literature?
Part 2 of SCM H1472 states: "Assign the free-floating subdivision
--Controversial literature under religions and their sects,
Christian denominations, and monastic and religious orders...". "Karaites--Controversial
literature" was assigned to certain works because Karaites are being treated
under this memo as a sect of Judaism. LC has treated the subject
heading "Jews" as a heading for an ethnic group, and so, we would not assign
"Controversial literature" as a subdivision under that heading.
