I agree with Bob that I would be good to add Carrier Types for both: - audio/computer disc - video/computer disc
This would allow us to distinguish between discs that can *only* be played in an audio device (if such exist) and those that can be played in either an audio device or a computer device, and ditto for video/computer discs. For Jenny's example, if we had these hybrid disc terms, it would result in: ----- Content Type: spoken word Media Type: audio Media Type: computer Carrier Type: audio/computer disc Content Type: text Media Type: unmediated Carrier Type: volume Extent: 1 CD Extent: ... pages ----- But until we get those new terms, it seems better to indicate that a thing can be accessed using either a computer device *or* an audio device, and therefore the disc is both a computer disc and an audio disc: ----- Content Type: spoken word Media Type: audio Carrier Type: audio disc Media Type: computer Carrier Type: computer disc Content Type: text Media Type: unmediated Carrier Type: volume Extext: 1 CD-ROM Extent: ... pages ----- Or to put it in MARC: ----- 300 $a 1 CD-ROM ... 300 $a ... pages ... 336 $3 CD-ROM: $a spoken word $2 rdacontent 337 $3 CD-ROM: $a computer $2 rdamedia 338 $3 CD-ROM: $a computer disc $2 rdacarrier 337 $3 CD-ROM: $a audio $2 rdamedia 338 $3 CD-ROM: $a audio disc $2 rdacarrier 336 $3 Booklet: $a text $2 rdacontent 337 $3 Booklet: $a unmediated $2 rdamedia 338 $3 Booklet: $a volume $2 rdacarrier ----- BTW, I ordered the MARC tags that way because it is easier to read--if your system reorders tags into numerical order, then they'll have to be in numerical order. And I entered the accompanying booklet in a separate 300, as per the LC RDA Training: Module3ExpressionsandContent s.20 But, I'm assuming we'd want to display the $3 in the OPAC so I added the colon even though s20 does not show doing so (as per LC-PCC PS 1.7.1, where guidance is provided for entering the $3 in 264 and 490, even though that PS does not mention the 33X fields) And '3.4.1.5 Other terms used to designate the type of unit' allows us to " Use a term in common usage (including a trade name, if applicable) to designate the type of unit: ... c)as an alternative to a term listed under 3.3.1.3, if preferred by the agency preparing the description." In an OPAC we would see something like this: ----- Extext: 1 CD-ROM Extent: ... pages Content Type: CD-ROM: spoken word Media Type: CD-ROM: computer Carrier Type: CD-ROM: computer disc Media Type: CD-ROM: audio Carrier Type: CD-ROM: audio disc Content Type: Booklet: text Media Type: Booklet: unmediated Carrier Type: Booklet: volume -------- Deborah - - - - - - - - Deborah Fritz TMQ, Inc. debo...@marcofquality.com www.marcofquality.com -----Original Message----- From: Resource Description and Access / Resource Description and Access [mailto:RDA-L@LISTSERV.LAC-BAC.GC.CA] On Behalf Of Robert Maxwell Sent: Wednesday, January 09, 2013 2:42 PM To: RDA-L@LISTSERV.LAC-BAC.GC.CA Subject: Re: [RDA-L] RDA media types I realize that is a workaround and as you point out it's been used as a solution, but it doesn't make logical sense to me. There is only one carrier involved here, not two (a single disc), and the disc is neither an audio disc nor a computer disc, but a hybrid. I'm just suggesting that RDA should recognize this sort of a carrier and include it in the list(s). Perhaps "multimedia" as a media type and "hybrid disc" as a carrier type. This is a fairly common kind of a disc that we're getting more and more of. Robert L.

The record shows "audio" and "computer" recorded as media types and "audio disc" and "computer disc" recorded as carrier types, even though there is only one carrier. This shows that it is allowed to record more than one term for these elements even if the various types are represented on a single carrier. I don't have a problem with that and rather welcome this flexibility but I realize that it might create problems when recording the extent since it is based on the type of carrier (3.4.1.3 "Record the extent of the resource by giving the number of units and an appropriate term for the type of carrier as listed under 3.3.1.3."). Unfortunately, RDA doesn't tell you how to choose the "appropriate term" when more than one type of carrier is possible for a single carrier. This is not problematic when one type of carrier is clearly predominant (e.g., in the case of an enhanced CD when the computer files are secondary) but in the case of an MP3 CD like the one that Jenny is talking about, it would help to know on which carrier type the extent should be based, given that both "audio disc" and "computer disc" are possible.

This does point to a problem that needs to be addressed in RDA, however. There isn't a mixed media/carrier type for these sorts of discs that can contain computer files, text, audio, motion picture, etc. Bob Robert L.

It's a 'learn to speak French' resource, consisting of a CD-ROM and booklet. The CD-ROM is also MP3 compatible and will play on suitable CD players. We have given it the following 33Xs: 336 $a text $2 rdacontent 336 $a spoken word $2 rdacontent 337 $a computer $2 rdamedia 337 $a unmediated $2 rdamedia 338 $a computer disc $2 rdacarrier 338 $a volume $2 rdacarrier We also wondered about 337 $a audio, but without a separate carrier that didn't seem right.
