The title proper includes the short title and alternative title, the numerical designation of a part/section and the name of a part/section.

The field may contain inclusive dates (subfield $f) and bulk dates (subfield $g) pertaining to a collection. For collections with no formal bibliographic title, subfield $k (Form) is used.

FIELD DEFINITION AND SCOPE

Varying forms of the title appearing on different parts of an item or a portion of the title proper, or an alternative form of the title when the form differs substantially from the title statement in field 245 and if they contribute to the further identification of the item.

For items including several works but lacking a collective title, field 246 is used only for titles related to the title selected as the title proper, usually the first work named in the chief source of information. Titles related to other works are recorded in field 740 (Added Entry-Uncontrolled Related/Analytical Title) or one of the other 7XX (Added Entry) fields.

When displayed/printed as a note, varying forms of titles are usually preceded by an introductory term or phrase that is generated as a display constant based on the second indicator value."
