Miscellaneous Materials
In addition to the separate issue of volume title-pages, lists of contents,
and indexes, periodicals are likely to spawn numerous promotional materials,
special supplements, calendars, and other miscellaneous materials. Volume
title-pages and other materials closely identified with the number(s) presented
in the description are of obvious interest, and should be treated in some
detail; materials that are less closely connected with the number(s) under
consideration can simply be mentioned, with sources of further information
provided.
