This subfield contains a term indicating the broad class of material to which the item belongs given in the language and script of the agency preparing the record.

The section or part name for items which are identified by a common name and a subsection name (see examples 3, 7, 30). Repeatable for each subsection or lower level division (see examples 9, 31, 32) and for a parallel part number. For detailed information see Appendix D .

The time period that relates to the creation, assembly, accumulation, and/or maintenance and use of the resources in the unit being described when required as part of the title. It may be the span of the earliest and the latest dates of the resources in the collection (see examples 14, 33), single date, if all the resources of the collection were created during the same year (see example 17), or dates separated with commas, if there is a significant gap in the chronological sequence of the resources of the collection (see example 15). Estimated date may be given, if necessary.

Dates pertaining to the majority of the resources in the unit being described if they differ significantly from the inclusive dates in subfield j (see example 16).

Coded identification of the language of a parallel title that appears in subfield d (see examples 4, 11). If subfield d is repeated, this subfield should be repeated, the languages identified reflecting the order of the parallel titles. This subfield and any repeats should always come last in the field.

Parallel data appearing on the item, i.e. data repeated in other languages or script, is denoted in ISBD by the use of equals sign. The equals sign is always at the start of any block of parallel data. The subfield d identifier will generate "= " automatically, and at the start of any other subfield it must be entered explicitly.

The general material designation is entered in the language of the agency preparing the record. Lists of general material designations are found in ISBDs. When an item has a collective title proper and comprises more than one interdependent component parts belonging to distinct material categories, the designation should be entered like "Two media", "Multimedia" or "Kit", which will indicate the distinction of materials.

If a title of a record is made of grammatically connected titles of individual works, a conjunction is entered in a subfield of the title introduced by the conjunction (see example 5).

Missing data are designated with "... [et al.]" or with an adequate expression in non-Latin script (see example 23).
