I would like to know all there is to know about extensions to the
UNIX Refer format for bibliographic entries.  I have seen several
partial extensions including reuse of fields (e.g., the %M field),
multiple uses of fields (e.g., %N being used for issue number and
report number), and the addition of fields (e.g., %0 - %9, and even
multi-character field names).  As far as I can tell, none of our
versions of Refer programs support any of these; maybe there is
some freeware that supports certain extensions.  Finally, I would
like to know about formatting conventions for longer fields, like
the abstract: How are super/subscripts, italic/bold, and footnotes
and reference notes represented?  Are troff codes the only convention?

I have another 20 questions, but I will save these for the brave
few who will reply.
