The following cataloging tutorial was provided by the honorable Janet Schrader, Bibliographic Services Supervisor:

This week’s MARC Monday topic is fields that provide more information about the work, the 538 and 546 fields. These are found mostly in records for non-print works, particularly video recordings and computer software. It is particularly important to pay attention to these when cataloging DVDs to be sure you item matches the screen format and subtitles.

The 538 field is used for system details such as what may be required to access the work as well as technical information about video format and sound reco


g playback.
