⮚Fixed-Length Data Elements & Leader
...
Field 007 carries coded data relating to the physical characteristics of the microform. CONSER Standard Record guidelines require only the first two elements: category of material (007/00 or $a: always “h” for microforms) and Specific material designation (007/01 or $b). Some institutions may desire to code all elements, depending on the needs of their users and staff. (CCM:32.2.1g)

⮚The preferred source
The preferred source of description is the Title frame (RDA 2.2.2.2). If there is no title frame, an eye-readable header, commonly found on microfiche, may be used as a substitute. If the title on the header is given in an abbreviated form, or, as is the case with most microfilms, if there is no eye-readable header, the container or accompanying material may be substituted as the preferred source.
⮚Title proper (245).

⮚Publication Information.
Sources for the micropublisher, distributor, and/or manufacturer are generally the microform title frame, container, the micropublisher's accompanying printed sales information, or the micropublisher’s web site. Sources from outside of the resource itself must be bracketed. If no information is available, input [Place of publication not identified] : $b [Publisher not identified] in the appropriate 264 field.
⮚Physical description (Extent, Content, Media & Carrier Type).
Following the extent, always provide the “content type” (RDA 6.9; field 336), “media type” (RDA 3.2; field 337), and “carrier type” (repeating the same term used in 300, this time in singular form) (RDA 3.3; field 338).
