In reply to your question about handling annual issues of periodicals, here
at the Bentley College library we recently decided to keep the annual issues
in with the rest of the issues of those titles. We did, however, decide also
to have some catalog access, and have made for each annual issue a record
on our online system giving the title, the title of the journal, and at least
one subject heading, and the location indicator for Periodicals Room. It seems
to be working well, and we reference librarians also like the subject access
via subject headings of our own choosing.
I hope this helps you!
