Values for Material Type

Material Type is used in the Central Catalog for search limiting and to express the physical format to users. Material Type is typically derived from Type of Record (Leader byte 6), except for "s" (journal/periodical) and "z" (thesis/dissertation).

Locally defined codes may be input in BCODE2 to override the standard values. Beginning in the summer of 2016, these local codes are now mapped to the standard set of material types used in the Central Catalog (below).

The following Material Type values are defined in the Central Catalog. More about: sound recordings and computer files.
