DCM Z1: 644 Series Analysis Practice
LC series practice: As of June 1, 2006, LC does not create or update SARs.
PCC series practice: Transcription of the series statement is mandatory if applicable. Searching for series authority records, tracing the series, and the creation and maintenance of series authority records are optional.
National-level PCC default analysis practice = "analyzed in full":
A PCC library can vary from the default analysis practice for reasons of local needs, preferences, or resources.
Recording PCC local analysis decisions
A PCC participant has the option to include or omit its analysis practice when creating or modifying an SAR. Only one PCC participant may include its analysis practice in an SAR.
Exception to analysis practice
Sometimes the exception to the analysis practice will apply to all the volumes of a serial analytic or to all the volumes of a subseries. In such cases, in subfield $b give the title of the serial analytic or of the subseries instead of the series numbers of those items.
644 ## $a n $b [Title of serial] $5 ___
646 ## $a c $5 ___
Change of decision
When there is a change in analysis practice and the classification practice already is classified as a collection (646$a = c), use a processing date as the cut-off. For subfield $d in the two 644 fields use the phrases "items processed after [date]" and "items processed before [date one day later than date in the previous subfield $d]." For example, if the analysis decision change was made on Feb. 3, 1993, give these 644 fields:
644 ## $a n $d items processed after Feb. 2, 1993 $5 ___
644 ## $a f $d items processed before Feb. 3, 1993 $5 ___
644 ## $a c $5 ___
When there is a change in analysis practice and the classification practice has been classified separately (646$a = s), use a numbering/chronological designation as the cut-off; use the term(s) from the item itself. For subfield $d in the two 644 fields use the designation of the latest analyzed volume in the database as the ending volume in the second (earlier practice) 644 field and the next number as the beginning volume in the first (current practice) 644 field. Generally, the same cut-offs are used in the 646 fields. Even if some volumes are not in the library, give the cut-off information using definite beginning and ending numbers. Do not show gaps in the subfield $d information; the person handling one of those "missing" volumes later needs to know what treatment to use.
items in hand: no. 18-20
analyzed vols. in database: no. 1-16
existing SAR:
644 ## $a f $5 ___
646 ## $a s $5 ___
revised SAR:
644 ## $a n $d no. 17- $5 ___
644 ## $a f $d no. 1-16 $5 ___
646 ## $a c $d no. 17- $5 ___
646 ## $a s $d no. 1-16 $5 ___
If volumes were cataloged out of order and now the analysis practice is being changed to "not analyzed" with a change in classification practice to "classed as a collection," consider recording the specific volumes for each analysis practice instead of reclassifying already-cataloged volumes. Give the new analysis practice in the first 644 field; use a hyphen with the last number to indicate that all volumes after that number should have the same treatment.
already analyzed: no. 1-4, 6-7
being processed now with "not analyzed" decision: no. 5, 8-10
existing SAR:
644 ## $a f $5 ___
646 ## $a s $5 ___
revised SAR:
644 ## $a n $d no. 5, 8- $5 ___
644 ## $a f $d no. 1-4, 6-7 $5 ___
646 ## $a c $d no. 5, 8- $5 ___
646 ## $a s $d no. 1-4, 6-7 $5 ___
already analyzed: v. 1-23, 25, 27-32
being processed now with "not analyzed" decision: v. 24, 26
existing SAR:
644 ## $a f $5 ___
646 ## $a s $5 ___
revised SAR:
644 ## $a n $d v. 24, 26, 33- $5 ___
644 ## $a f $d v. 1-23, 25, 27-32 $5 ___
646 ## $a c $d v. 24, 26, 33- $5 ___
646 ## $a s $d v. 1-23, 25, 27-32 $5 ___
Non-analyzable volumes
If the publication began as a not-analyzable serial and then became a monographic series without changing its title, create one SAR. Give two 644 fields and a 667 note that explains the change in the publication.
644 ## $a f $d v. 9- $5 ___
644 ## $a n $d v. 1-8 $5 ___
645 ## $a t $5 DPCC $5 ___
646 ## $a c $5 ___
667 ## $a Lacked analyzable titles until v. 9.
If a later volume of an existing analyzed-in-full series is not analyzable, consider creating an analytic record for the volume according to the guidelines in LC-PCC PS 2.3.1.7 instead of modifying the 644 field to indicate this fact.
