MARC Displays

This type of display is used by the Library of Congress catalog.

This type of display is used by OCLC's Connexion database.

These two figures are displays of the same MARC record. Several differences can be observed if one compares them:

• The 008 field is displayed as one string of characters directly out of the MARC dump in the LC record, but in the OCLC record it is displayed on four lines with meaningful parts of the string preceded by labels (the OCLC display also show some values from the MARC Leader as well).

• The LC Control Number at the beginning of the LC record has been retagged as 010 in the OCLC record and is displayed with a hyphen instead of two zeros.

• The position of the 020 and the 040 fields are switched in the two records. Note: In a MARC record, not all fields are in numerical order!

• The LC record displays subfield $a, but the OCLC record does not. Subfield $a, obviously, is still in the OCLC record (the same data is thre), but the subfield designation is not presented on the screen.

• The LC record does not show blank spaces inserted after the subfield codes and the indicators as the OCLC record does.
