Monographic component part:
A monographic bibliographic unit that is physically attached to or contained in another monographic unit such that the retrieval of the component part is dependent on the physical identification and location of the host item or container. Examples of monographic component parts with corresponding host items include an article in a single issue of a periodical, a chapter in a book, a band on a phonodisc, and a map on a single sheet that contains several maps. The record contains fields that describe the component part and data that identify the Host Item Entry (field 773).
Code a in Leader/07 indicates that the bibliographic level of the record is a monographic component part.
