if no one part dominates:
either make a separate entry
for each part (see also rule
7B16)
or give all the titles in the order in which they appear
in the chief source and make added entries for all the parts
other than the first name as instructed in rule
29B8.
If you are making on entry for the bibliographic
resource and all the parts are manifestations
of work by the same person(s) or body (bodies),
separate the titles by space, semicolon, space
( ; ).
If you are making one entry for the bibliographic
resource and the parts are manifestations of work
by different persons or bodies, give the titles
and statements of responsibility in the order
in which they appear in the chief source. Separate the
titles and statements of responsibility of one
part from those of another by a full stop followed
by two spaces (. )
