Examples of 0XX's
Here is an example of the use of these fields from the sample MARC record at the beginning of this course:
010 $a 99011493
020 $a1563087723 (hardbound)
020 $a1563087022 (softbound)
050 00$aZ675.S3$bW8735 1999
In this example, the 010 tag indicates a control number assigned to this record by the Library of Congress. Following that field are two entries for 020, the ISBN number. (Note that some tags may be used more than once in the same record.) One of these entries is for a hardbound version of the book, and the other is for a paperback version. The 040 field in the example indicates the cataloging source to be DLC, or the Library of Congress. The three subfield codes indicate ‘a’ the original cataloging agency, ‘c’ the transcribing agency, and ‘d’ the modifying agency. The 043 field is the Geographic Area Code, here indicating that the cataloging was done in the United States.
The Library of Congress call number assigned to this work is listed in the 050 field. The two indicators ‘00’ show that the item is in the Library of Congress and that LC assigned the classification number. The two subfields shown are ‘a’ classification number, and ‘b’ item number (the author number used by LC). The last field shown in this section is 082, the Dewey Decimal call number. The indicators used here, ‘00’, show that the full edition of Dewey was used and that LC assigned the number. The subfields shown are ‘a’ classification number, and ‘2’ edition number, indicating that the classification number was created using the 21st edition of Dewey. This is one of the rare uses of a number as a subfield code.
