The CONSER Cataloging Manual (Module 5, p.11-12) deals with your problem of
130 corporate body qualifiers as follows:

     Dates may be used alone or with the place or corporate body.  As a
     rule, give the date with the place or corporate body when the SAME
     serial, in changing its title, repeats an earlier title.

     If two DIFFERENT serials are issued in the same place, generally
     prefer to qualify by the corporate body.  Use place and date only when
     there is no corporate body or term that will distinguish the serials.
