The cataloging source code indicates the source of the original cataloging record.

Records input by National Libraries in CONSER (Library and Archives Canada, Library of Congress, National Agricultural Library, National Library of Medicine) are coded as "#" (blank).

Other CONSER participants should code records as "c" (defined as "cooperative cataloging program") in all records - original and copy - newly authenticated and distributed as part of the CONSER Program, unless the record began as a record from a national library, in which case the source code will remain "blank".

CONSER participants do not change the existing code when further updating a previously authenticated CONSER record.  Previously, authenticated records based on existing copy were coded "d" (defined as "other") by default.  Once set to a code other than "u", this element cannot be changed.


Code definitions

#    National bibliographic agency.

This code is used by the Library and Archives Canada, Library of Congress, National Agricultural Library, National Library of Medicine, and other national libraries for their original cataloging and by other institutions when transcribing from cataloging copy created by one of these agencies.

When inputting a record from LC cataloging copy and using code "#", the database record must reflect:

a)   the LC choice of entry;

b)   the cataloging code and type of cataloging done by LC (i.e., successive entry);

c)   all the information as found on the LC copy being transcribed (although such information may be updated by the inputting institution).

c    Cooperative cataloging program.

Code "c" is used by participants in the CONSER Program (other than national bibliographic agencies).  Formerly, all non-LC CONSER records were coded as "d."

d    Other.

This code is used by institutions that are not national bibliographic agencies or participants in a cooperative cataloging program, and also by CONSER institutions when inputting a record but not authenticating it for CONSER.  This code was formerly used by CONSER participants when inputting original cataloging.

u    Unknown.

This code is not used in CONSER records.  OCLC online validation rules disallow code "u" when there is an 042 field with a CONSER authentication code.  CONSER participants should determine the source of all cataloging and input the appropriate code.

The code has often been used when an organization transcribes manual cataloging data from an unknown source.  In this case, field 040 lacks a subfield $a and subfield $c contains the MARC code for the transcribing organization.  In order to pass OCLC validation rules in authenticating the record, the cataloger may need to add the same MARC code in subfield $c of the 040 to subfield $a, then add the appropriate code to the 008/39 ("d" if the 040 subfield $a MARC code is non-CONSER, "c" if CONSER).

If a record already on the data base contains code "u" and a participant has LC copy for that title, code "u" may be changed to the appropriate LC-related code.

CONSER use of 008/39 (Cataloging source) codes in serial records (except by National Libraries) as of May 1, 2009


Value in 008/39

New CONSER Record


Previously Authenticated Record


Previously with "blank" in 008/39


Previously with "c" in 008/39


Previously with "d" in 008/39


Previously Non-Authenticated Record


Previously with "blank" in 008/39  *

blank  *

Previously with "c" in 008/39


Previously with "d" in 008/39


Previously with "u" in 008/39


*   Retain value "blank" because the previously non-authenticated record is a transcription of a national library's record.  Use value "c", instead, if you believe that is not the case and value "blank" is a coding error.

NOTE:  National Libraries in CONSER (Library of Congress, Library and Archives Canada, National Library of Medicine, etc.) are continuing after May 1, 2009, the same practices for coding 008/39 for original and previously unauthenticated OCLC records as they applied before then, rather than the ones shown above.
