Description/Instructions

Field 012 is a local field used by authenticating agencies for certain elements in the leader, communications area, and fixed fields of the LC internal format. The field is also used for additional control elements that cannot be input or displayed in the fixed field area of the OCLC record.

Separate subfields are input in this field. Only those subfields that are input are displayed. Default values are defined for each subfield. If the subfield is not input, the default value for that subfield is output to LC. The entire field is output on tape from OCLC to LC as a single subfield $a composed of 26 positions (15 different data elements).

Two of the data elements output (positions 6-11 and 12-15) are generated by the OCLC system. These two elements, the NSF Special LC Projects indicator (5th position) and the ISSN distribution (24th) through Communication with USPS (27th position) have no corresponding fixed field positions in the LC internal format. Subfield $z may be input online in the 23rd position, but it is not output as part of the 012 field.

At LC, each data element is converted into its corresponding position, if any, in the LC internal format. The entire 012 field is also retained in the LC record, but it is not distributed by LC.

CONSER Participants are responsible only for the following subfield:

$b Codes "0" or "7" must be changed to "3" when modifying an LC-authenticated record.

Definitions of character positions/subfield codes

1/$a Priority byte.

This byte is no longer input.

2/$b Non-permanent distribution code.

0 Suppress distribution of cards to LC; Suppress distribution of tape record; Suppres Videocomp update. (To specify classified material, etc.)

1 Suppress distribution of cards to LC; Suppress distribution of tape record; Allow Videocomp update.

2 Suppress distribution of cards to LC; Allow distribution of tape record; Suppress Videocomp update.

3 Suppress distribution of cards to LC; Allow distribution of tape record; Allow Videocomp update.

4 Allow distribution of cards to LC; Suppress distribution of tape record; Suppress Videocomp update.

5 Allow distribution of cards to LC; Suppress distribution of tape record; Allow Videocomp update.

6 Allow distribution of cards to LC; Allow distribution of tape record; Suppress Videocomp update.

7 Allow distribution of cards to LC; Allow distribution of tape record; Allow Videocomp update.

LC uses this code to control distribution records from CDS to subscribers. Code "3" is the default value.

NOTE: This byte is not automatically reset by the machine. Each time a correction is made, this byte must be re-checked to ensure that the current code is still applicable. CONSER Participants making permissible changes to LC-authenticated records should reset the $b to "3" or delete $b entirely if any other value is present. If subfield $b is deleted, OCLC will supply the default value to LC on output.

3/$c Major/minor change byte.

This byte is no longer input.

4/$d Permanent distribution code.

This byte indicates the permanent mode of distribution: 1) the distribution of LC cards to catalogs; 2) the distribution of the tape record to subscribers; and 3) the updating of the Videocomp data base. The codes for this byte are the same as those for the 2/$b - Non- permanent distribution code. See that item for a description of the codes.

If not input, this position defaults to code "7".

5/$e Special LC Projects.

This position indicates whether a record was claimed for projects, such as NSDP's National Science Foundation Project ("n") or the Special Claiming Project ("s"). If both codes are applicable, "s" takes precedence. If neither code is applicable, the position defaults to a hyphen.

6-11 Dates of last transaction.

12-15 Daily transaction number.

Bytes 6-11 and 12-15 follow $e but are not designated by any alphabetic subfield code. Both are automatically generated by OCLC. Neither appears on the OCLC display. Both appear on the LC ILS display.

The dates of last transaction, in the form of YYMMDD, is automatically assigned to all records processed during a given day at OCLC.

The daily transaction number is a sequential number automatically assigned each time a transaction occurs during a given day at OCLC.

16/$f OCAT certification. [Obsolete]

This byte was defined to indicate whether or not the record being processed was checked against the LC Official Catalog. At present, all records are output by OCLC with the default value "-" regardless of status.

17/$g Type of cataloging code.

p Printed card cataloging

f Form card cataloging

s Serial Record preliminary cataloging

o Outside library report

a Amalgamation (may be used with retrospective records only)

This position was defined to indicate the type of cataloging from which the MARC record is derived. At present, all records are input using the default value "p".

18/$h Non-established name indicator.

This position indicates whether or not corporate or personal names in the record are established in the Official Catalog. If one or more names in the record are not established in the OCAT, an "x" should be input.

NOTE: This position should only be used when MARC input consists of records not given printed card cataloging by LC. The byte defaults to a hyphen, indicating that all names in the record are established.

19-22/$i NST publication date code. [Obsolete]

Prior to 2000, a date was added to $i to report holdings to New Serial Titles. This practice has been discontinued since New Serial Titles ceased with the 1999 subscription year. The four position code carried the year and month in YYMM format; for example, September 1984 was input as 8409. The date code was used to select a record for publication in NST and to prevent the automatic republication of the record each time it was updated.

Records authenticated prior to 1984 did not contain 012 $i, nor was one added later, unless an 850 field was being added for the first time. Beginning with format integration in March 1996, records for non-print serials were no longer included in NST and did not require an 012 subfield $i.

23/$z Record status overrider.

d Deleted record

This position is used only to input code "d" to override the record status on output to LC. (For instructions on the use of code "z" to deauthenticate records, see C2.) This code does not change the record status code as it is displayed on the OCLC data base.

There is no default value defined for this position.

Code "d" is used whenever LC deletes a record from the LC distribution data base. Value "d" in this position changes the record status to "d" for output to LC and for distribution by LC. The record, however, is not automatically deleted from the OCLC data base.

Subfield $z containing code "d" should never be deleted from a record except in a situation where the record is being reused and redistributed with a different card number in subfield $a of field 010.

Code "n" and code "a" are no longer used in this subfield. LC's internal programs ensure that the record status is correctly set to code "n" when necessary. OCLC's programs automatically handle the setting of code "a".

When making corrections to a record that is already authenticated, CONSER Participants should always check to ascertain whether subfield $z is present in field 012. If the subfield is present and it contains code "n" or "a", delete the subfield.

24/$j ISSN distribution.

This element, to be used only by NSDP, controls selection of records as new, modified, or deleted for the file maintained by the ISSN International Centre (ISSN IC).

- or # New record (default value)

Used for all records being authenticated by NSDP (except those coded "X"). If all other selection criteria are met, records with these values are distributed to the ISSN International Centre which will add them to the ISSN file as new records.

0-9 Modified record (used only for records with ISSN center code (008/20) value set to "1")

Used to indicate that ISSN-related data elements have been added, changed, or deleted in an NSDP-authenticated record, requiring updating of the ISSN file.

When the first such modification is made, the value "0" is used. On each successive occasion when one or more data elements is modified, the value is increased by one, e.g. "0" is replaced by "1", which in turn will be replaced by "2", etc. The cycle can be repeated as often as necessary.

If all other selection criteria are met, records with these values are distributed to the ISSN IC, which updates its files if the value is different from the one in the record it has in its file.

d Deleted record (used only for records with ISSN center code (008/20) value set to "1")

Used to replace value "-", "#", or "0"-"9" when a previously authenticated record is to be deleted from the ISSN file. If all other selection criteria are met, records with this value will be distributed to the ISSN IC, which will delete the record from its file. This code is currently not used by NSDP.

P A & I Project record

Used during the project for titles authenticated by NSDP without surrogate or piece in hand.

X Ineligible record (used only for records with ISSN center code (008/20) value set to "1")

To be used when a record should not be distributed for some reason, e.g., provisional authentication (Cf. field 042). Records with this value will not be distributed to the ISSN IC even if all other selection criteria are met. This value may be replaced by value "-" or "#" if the ineligibility is of a temporary nature.

T Foreign record request

To be used to indicate that NSDP has requested assignment or verification of an ISSN for the title represented by the record. Such records are not authenticated by NSDP until the ISSN assignment or verification is received by NSDP, at which time "T" is replaced by "#".

25/$k ISSN on publication.

This element, to be used by NSDP catalogers only, indicates whether the ISSN is printed on the publication.

- or # Unknown; not appropriate, not NSDP's responsibility

These codes will be used for titles already in the database and dead or foreign titles lacking ISSN on issues.

0 Incorrect ISSN on publication

Defined but not used by NSDP at this time.

1 Correct ISSN on publication

When suitable documentation becomes available, NSDP will change value "#", or "0" to "1".

26/$l Communication with publisher.

This element, to be used by NSDP catalogers only, indicates whether the publisher either specifically requested or has been given the ISSN.

- or # Unknown; not appropriate, not NSDP's responsibility.

0 Efforts to contact publisher were unsuccessful. Defined but not used by NSDP at this time.

1 Response sent to publisher's request.

a Unsolicited notification letter sent to publisher.

b Unsolicited notification letter sent to publisher (standing customer). Inactive code; generally will be converted to "a" upon reaccess of the record.

c Unsolicited notification letter sent to publisher in CRS project. Inactive code; generally will be converted to "a" upon reaccess of the record.

f Unsolicited notification letter sent to publisher in Folio project. Inactive code; generally will be converted to "a" upon reaccess of the record.

y Notice of incorrect ISSN sent to publisher. Subfield "$y" should be present in field 022 also.

p Incorrect use of ISSN corrected by publisher; issue received by NSDP. Subfield $k value "1" should also be present in field 012.

r Renotification letter sent to a publisher who previously requested an ISSN but not printing it on the most recent issue seen.

X Do not give ISSN to publisher (applies only to contested titles).

27/$m Communication with USPS.

This element, to be used by NSDP catalogers only, indicates that the title is mailed at second class rates and that the ISSN has been reported to the U.S. Postal Service.

- or # Unknown; not appropriate. These codes should be used for all titles not reported to the USPS.

0 ISSN reported to USPS for a title whose second-class permit is pending. When the permit is issued, the six-digit USPS number will be entered in field 32 and this value will be changed to "1".

1 ISSN reported to publisher via USPS. To be used when the title is mailed at second class rates and the ISSN is reported to the U.S. Postal Service. When this value is used, the six-digit USPS number will be entered in field 32.

c Controlled circulation title (inactive code; generally converted to "1" upon reaccess of the record).

d Title deleted from USPS active file; USPS permit abandoned or title ceased.

r Renotification sent to publisher via USPS.

x No ISSN reported to USPS (applies only to titles where USPS and NSDP treatment differ).

y Notice of incorrect ISSN sent to publisher via USPS. Subfield "$y" should be present in field 022 also.

p Incorrect use of ISSN corrected by publisher; issue received at USPS work station. Subfield $k value "1" should also be present in field 012.
