Recording Cataloging Source Information
 

Information pertaining to the source of the cataloging is recorded in the following fields in the bibliographic record: 

SRC Cataloging source code 

    blank  Library of Congress 
    d  Other
010 Library of Congress Control Number (LCCN) 

040 Cataloging source 

    $a original cataloging agency 
    $c transcribing agency 
    $d modifying agency
1. For items cataloged by Yale: 
    SRC = d 
    [No field 010] 
    040 $a CtY $c CtY 
    "Yale cataloging" means that the record was created by Yale. 
2. For items for which we have used LC cataloging: 
    SRC = blank
    010 = LCCN 
    040 $c CtY 
    "LC cataloging" means that the record was created by LC and we have used it to describe the same item in our collection. 
3. For items for which we have modified LC cataloging: 
    SRC = blank
    010 = LCCN 
    040 $c CtY $d CtY 

    "Modified LC cataloging" means that (1) the record was created by LC (2) we have made changes to the record to accommodate the item in our collection and (3) the LCCN is still accurate. 

    Examples of changes that would not affect the accuracy of the LCCN are the addition of subject or other added entry headings and/or the changing of a heading to AACR2 form. 

4. When in doubt about the source of cataloging: 
    SRC = d 
    [No field 010] 
    040 $a CtY $c CtY 

    Assume "Yale cataloging" when (1) the record was created by LC (2) we have made changes to the record to accommodate the item in our collection but (3) the LCCN is no longer accurate. 

    Examples of changes that would affect the accuracy of the LCCN are those that involve fields 245, 250, 260, 300, 4xx, and, in some cases, 5xx.  Assume "Yale cataloging" when information in any of these fields has been modified. 

LC cataloging: 

"LC cataloging" means that the record was created by LC and we have used it as is to describe the same item in our collection. 

    SRC = blank
    010 = LCCN 
    040 $c CtY  
Modified LC cataloging: 

"Modified LC cataloging" means that (1) the record was created by LC (2) we have made changes to the record to accommodate the item in our collection and (3) the LCCN is still accurate. 

    SRC = blank
    010 = LCCN 
    040 $c CtY $d CtY 
    Examples of changes that would not affect the accuracy of the LCCN are the addition of subject or other added entry headings and/or the changing of a heading to AACR2 form. 
Yale cataloging: 

Assume "Yale cataloging" when (1) the record was created by LC (2) we have made changes to the record to accommodate the item in our collection but (3) the LCCN is no longer accurate. 

    SRC = d 
    [No field 010] 
    040 $a CtY $c CtY 
     
    Examples of changes that would affect the accuracy of the LCCN are those that involve fields 245, 250, 260, 300, 4xx, and, in some cases, 5xx.  Assume "Yale cataloging" when information in any of these fields has been modified.
