Definitions of Terms (76X-79X Linking Entry Fields - General Information)
Definitions of terms used in the linking entry fields are:
Target
item: A bibliographic item that is the principal or primary
unit covered by the description for which the record was constructed.
The target item is the item to which the data in character positions
06 (Type of record)
and 07 (Bibliographic
level) of the Leader, and field 245 (Title
Statement) apply.
Related
item: A bibliographic item that has either a chronological,
horizontal (different versions), or vertical (hierarchical) relationship
with a target item, and for which the linking entry field is formulated.
Component
part: A bibliographic item that is physically part of another
bibliographic item such that the retrieval of the part is dependent on
the physical identification and location of the host item (e.g., a chapter
in a book, an article in a journal).
Constituent
Unit: A bibliographic item that is part of another item.
The constituent unit is physically separate from the item of which
it is considered a part.
Host
item: A bibliographic item that either physically contains
(as in the case of the component part), or bibliographically includes,
(as in the case of a constituent unit), the subpart that is the target
item for the record. For example, if a record describes a journal
article, the host is the journal; if a record describes one digital item
in a set, the host is the set.
Chronological
relationship: The relationship in time between bibliographic
items (e.g., the relation of a serial to its predecessors and successors).
Horizontal
relationship: The relationship between versions of a bibliographic
item in different languages, formats, media, etc.
Vertical
relationship: The hierarchical relationship of the whole
to its parts and the parts to the whole (e.g., a journal article to the
journal in which it is published; the collective title of conference proceedings
and the individual titles of contributions it brings together; a subseries
and the main series to which it is related).
