The examples given in the MARC manual for Holdings 853 $a-f seem to
assume that the type of enumeration is numeric i.e., vol. 1 no. 4.  But
some serials have other types of enumeration: alphanumeric, ordinal,
roman, etc.  Where in the Holdings record do I specify type of
enumeration?  If I don't specify, then how does the system recognize
that after pt. B comes pt. C?

Thank you
