006 Additional material characteristics. Optional as needed
Use this optional field when a collection has substantial characteristics of a form of material that is additional to the main one entered in LDR/06. It is like an extra >008 field (>008 being non-repeatable) and allows for additional searching by format.
For example, the archivist might use it to capture the fact that an otherwise textual manuscript collection contains a significant amount of drawings. It is recommended that an 006 be added when you have a series of materials not represented in the 008, or if you find the bulk substantial enough to mention the type in the >300 field.
