Authority 644 szerkesztése (szakasz)

==Példák:==

One-character alphabetic code that indicates a specific organization's analysis 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 practice applies.

Code specifies whether all, some, or none of the volumes of a series are analyzed for bibliographic records. Field 644 is not used to indicate that a series-like phrase is not analyzed. Varying analysis 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 644 fields.
