Posted on 2 lists.  I apologize for duplication.

I have a question about an old title change I am cleaning up.  I
looked at the title Business Mexico (OCLC# 10535093), and "Business
Mexico (Mexico City, Mexico : 1991)  OCLC# 23709222.

Business Mexico (without the qualifier) is the first title,vol. 1,
no. 1 (Oct. 1983) 1983-v.7 (Dec. 1990).  Published quarterly. It
Merged with: Mexico update (which we do not have) to form the monthly
publication: Business Mexico (Mexico City, Mexico : 1991).  The
volume numbering starts over at vol. 1 (1991) with the new title.
Please note: the subject headings are the same, except for the new
heading:
651 0 Mexico $x Economic conditions $y 1994- $v Periodicals.
Both titles include among other identical headings:
651 0 Mexico $x Economic conditions $y 1982-1994 $v Periodicals.

As I was taught back in the days of catalog cards that you create
successive entry for identical titles, ONLY when the numbering
restarts at vol. 1, AND the subject matter has changed (besides the
times when an author changes or qualifier in 130 changes for
corporate author, etc.) Otherwise it just a numbering change.

In this case, since it was 15 years ago that it was cataloged and
today we are more into the "simplification" of cataloging, if this
title would have had "[New Ser.] Vol. 1, no. 1 added to the 362
instead of doing successive entry if you cataloged it? Or would you
do successive entry and why?

Comments?
