Bib, item, and course record connections

Question

How are bib, z30 (Item), z108 (Course), and course doc records connected to each other?

Answer

The xxx30 course doc record is connected to the ADM/item record via an ITM link if the item is owned by the library and has an xxx01 bib record. Otherwise, as in the case of a professor's copy, the link is an ADM-type link. These links can be seen in util f/3/12 ("Display Links Associated with a Record").

The xxx50 z108 (Course) record is linked to the xxx30 Course doc record via xxx30 z11 (Direct index) "CNO" and"CNO-S" index entries. These CNO fields can also be seen in the xxx30 Course doc record itself.

The Course doc record can be viewed in xxx30 util f/4.
