In the newly released PCC guidelines for relationship designators
http://www.loc.gov/aba/pcc/rda/PCC%20RDA%20guidelines/Relat-Desig-Guidelines.docx),
Guideline 14 says: "If a cataloger wishes to indicate a known
relationship to a known resource, and the $i relationship information
subfield is defined for the  MARC 7XX field being used, provide a
relationship designator. Do so even if the field coding otherwise
already expresses a relationship."

This sounds like it is now required of PCC (CONSER) records to include
$i in 76x-78x linking fields, for example:
780 00 $i Continues (work): $t Regional trends (London, England)
785 00 $i Continued by (work): $t Region and country profiles

Are mergers coded as:
785 00 $i Merged with: $t American electrician
785 00 $i To form: $t Electrical world (New York, N.Y. : 1906) ?

We wanted to confirm that this is now required and to be implemented
immediately. Although my library doesn't participate in CONSER, we
generally follow CONSER cataloging standards.
