Data elements are divided into the four groups of fields that describe captions and pattern, enumeration and chronology, textual holdings information and item information. These fields cater for four types of items as defined in the Record Label, i.e. single-part items, multipart items, serial items and integrating resources, although the most important application is for serial and integrating resources holdings. Within each set of fields, separate fields are defined for three categories, i.e. basic bibliographic unit, supplementary materials and indexes.
