Guide to Cataloging DVD and Blu-ray Discs Using AACR2r ... - OLAC

This section will not attempt to duplicate cataloging practice for single CD items that follow
AACR2 Chapter 6 or single DVD items that follow AACR2 Chapter 7. Instead, the
information presented in this section will clarify how to describe the DualDiscs in the fields
that may differ from the cataloging of single-format discs.
Chief Source of Information
As indicated in Chapter 6 for sound recordings, the chief sources of information are the disc
and label with preference for textual data to sound data. In Chapter 7 for DVDs, the chief
source of information is the item (e.g., title frames). If the information cannot be taken from
the chief source, use accompanying textual material which may be found in scripts,
publicity material, etc. and the container if it is not an integral part of the DVD. The
cataloger will make this determination when deciding whether the dominant content is
audio or video. Promotional material with an item may help determine if the item has been
marketed and created as a specific format (CD vs. DVD) with the opposite format as
supplementary material. If this cannot be determined, defer to cataloger judgment.
Leader
For the CD or DVD-Audio dominant DualDisc, use “i” or “j” as appropriate. For the DVD-
Video dominant DualDisc, use type “g.”
i = nonmusical sound recording
j = musical sound recording
g = projected medium
006 Fixed-length Data Elements – Additional Material Characteristics
Include information for the additional format (DVD-Video, DVD-Audio, or CD audio as
appropriate)
007 Fixed-length Data Elements – Physical Characteristics
Include information for the dominant and alternate formats as appropriate.
General Material Designation
The dominant content will determine whether the GMD will be [sound recording] or
[videorecording].
