FIELD DEFINITION AND SCOPE
One-character alphabetic code that indicates a specific organization's tracing practice
for a series named in the 1XX field of an established heading record for a series. May
also contain the volumes/dates and/or the institution/copy identification to which the
tracing practice applies.
Code specifies whether the series is used as a series added entry or as an untraced
series note in bibliographic records. Field 645 is not used to indicate that a
series-like phrase is not traced. Varying tracing practices for different ranges of
volumes/dates within a series, for different copies or sets within the same
organization, or for different organizations are contained in separate 645 fields.
