Serial component part:
A serial bibliographic unit that is physically attached to or contained in another serial unit such that the retrieval of the component part is dependent on the physical identification and location of the host item or container. An example of a serial component part with corresponding host item is a regularly appearing column or feature in a periodical. The record contains fields that describe the component part and data that identify the Host Item Entry (field 773).
