When one serial is issued with another and is also issued separately, use field 777 to link the two records (AACR2 12,7B12). Due to the complexity of most "issued with" relationships, field 580 is usually input to provide the note. Example:

Note: If a serial contains a section with its own title but the section is not also issued separately, give an added entry, but not a ;link, for the section (see also 14.4.4.).

If the included serial is no longer issued separately treat it as an absorption (780 X5) rather than an "issued with" relationship.
