RDA 3.2: GMD Processing

Retain or remove GMD

PCC guidelines for hybrid records recommends retaining the GMD (245 $h) until after March 31, 2016 to facilitate ILS display or discovery. To this end there are also options to add GMDs to records that are missing one. Options are available for excluding the addition of certain terms if desired.

Add missing GMD terms

MARS 2.0 also has the ability to add missing GMD terms. Current PCC standards recommend not adding missing GMDs to existing RDA records. However, we understand that this may be desirable in the short term for some libraries participating in the transition between AACR2 and RDA records.

The following table shows a sample of the 245 $h GMDs that can be added based on certain values:

245 $h	LDR Byte 06 Value	008 contains
[cartographic material]	e or f
[electronic resource]	m
[filmstrip]	g	byte 33 = f
[kit]	o
[microform]	a or t	byte 23 = a, b or c
[motion picture]	g	byte 33 = m
[slide]	g	byte 33 = s
[sound recording]	i or j
[transparency]	g	byte 33 = t
[vidoerecording]	g	byte 33 = v

To modify any values in this tables, please indicate any changes in Step 2-7.

General Material Designation (GMD) in some cases:

 original field:
   245 10 $a Olympia town square /$c by Fred Smith.

 updated field:
   245 10 $a Olympia town square $h [cartographic material] /$c by Fred Smith.

Note: $h (Medium) in other title fields and subfields are normally deleted in keeping with current cataloging practice (see the Subfield Deletes table in RDA 2.4).

Remove GMD terms

MARS 2.0 also provides the option to remove the GMD in the 245 $h if you no longer need it. This is not currently recommended by LC/PCC standards. However, if you do need to remove the 245 $h, you may wish to house it elsewhere temporarily. Please choose in either a generic 500 field or some other field within your record.

 
 original record:
   245  $a La vita di Maria $h [sound recording] :$b rappresentazione sacra per voci, coro e orchestra /$c Nino Rota ; Testi scelti e tradotti da Vinci Verginelli.
 
 updated record:
   245  $a La vita di Maria :$b rappresentazione sacra per voci, coro e orchestra /$c Nino Rota ; Testi scelti e tradotti da Vinci Verginelli.
   500  $a sound recording.

Default

Retain 245 $h GMD when it exists in the record.
