6.25.2 RDA definition and scope
6.25.2.1 An underlying physical material of a manifestation.
6.25.3 General rule
6.25.3.1 Record the base material of the manifestation if considered important. Use one or more terms from the RDA Value Vocabularies: RDA Material and indicate the source.
Example:
Base material: paper

6.25.3.23.Y.Y If a manifestation is known to have multiple applied materials but not all can be readily identified, record “mixed materials”.
6.25.3.25.Y.Y Optionally, in addition to “mixed materials”, record the materials that can be readily identified as Details of applied material (see 6.265.SOMETHING.SOMETHING).

6.26.6.Y.Y Still image resources
