RDA was created, as was said in the last chapter, to replace AACR2. MARC21 was created to replace all previous iterations of MARC. They were not created for the same purpose, but many of their fields (through certainly not all) overlap. For our purposes in this chapter, we will only consider the overlapping data pertaining to the MARC fields in the chapter heading.
In each field, the RDA term for the content, media, or carrier is in the $a subfield of the field. the MARC code, if needed, for the item is recorded in the $b subfield. The Leader symbol is recorded as part of the Leader of the entire record.
Field 336
This field pertains to the content of the item. In the MARC field, there are only three characters that can be put in the subfield. In the Leader, the first part of the MARC record, the content is defined by a single letter. RDA, on the other hand, can contain whole phrases, mostly two or three words, to describe the content in a resource. MARC allows for the integration of RDA data by allowing catalogers to put the RDA category of an item into a subfield.
Below is a reproduction of a map created by the Library of Congress:[1]

Field 337
This field contains metadata about the type of media, or the format, in which the information is presented to the user. This is not a record of the type of information container, or the item, but rather about the format (text, audio, spoken word, etc.). Again, RDA has more flexibility and descriptive restrictions than MARC.[2]

Field 338
This field contains information about the format of the item that contains, or carries, the information. For this reason, Field 338 is referred to as the Carrier Field. RDA Carrier types are extremely specific. Each format of the information (text, audio, unmediated information, etc.) requires specific types of carriers. For example, you cannot put an audio music file on a flipchart or a book. Therefore, information or data is carried on items that will accurately and consistently impart that information to a user. The tables below have again been taken from the Library of Congress. [3]
Unlike the other two 33X fields, 338 only allows two characters for an entry. Still, it incorporates the RDA data to allow humans to read the record.
This table includes all carriers of information that is presented in an audio format.

These carriers are all an iteration of a computer, whether it is a resource found online, a cartridge, or a compact or floppy disk.

You may notice that the carriers in the table below mostly have the prefix “micro-“. These carriers are formats that were recorded on a film so small that it could hold thousands of documents. Microfiche and microfilm are the most popular carriers of this category, but there are many others, as you can see below.

A separate category exists for microscope slides and other visual material created in a scientific lab.

Yet another category contains only those data carriers that project their data onto another material for proper viewing.

What exactly is a stereograph? This is an image that was made in duplicate for special viewing in a stereoscope. An individual looks through the stereoscope at two nearly-identical images. The result is that both eyes combine the image and create a more crisp picture than if both eyes had only viewed one image. The resulting image is almost three-dimensional in quality.

A user who works with items in this category, unmediated carriers, needs no external tools to be able to access their data. These carriers, especially $avolume$bnc, are the most common item sought after in a library.

While volumes and other unmediated carriers are the predominant resource sought after in a library, video carriers have become more sought after since the 1970s. Videocassettes (VHS or Betamax), video cartridges, and videodiscs (LaserDisc or DVD) are all examples of video carriers.

other | vz | z – 007/01 (Videorecording) |
Our final category of carriers has only one entry: unspecified. This is most frequently used in archives or other repositories who have no way of determining the type of item they are recording. Even by archival standards, this would be grounds for refusing to accession an item (if it is donated) or deaccessioning (if the item has previously been in the collection).
