Definition

Physical description information for an item that requires technical equipment for its use, and/or more granular description information of an item's material properties to facilitate access and discovery or to support collection management. Coded physical information is contained in field 007.

Guidelines

Prefer use of a separate field for each unique term. For example, for a charcoal drawing on canvas in a wood frame:

 
340     canvas ǂ2 rdamat
340     ǂc charcoal ǂ2 rdamat
340     ǂe wood ǂ2 rdamat

For a color ink self-portrait on rice paper:

340     ǂ3 self-portrait ǂa rice paper
340     ǂ3 self-portrait ǂb 18 x 23 cm
340     ǂ3 self-portrait ǂc colored inks
340     ǂ3 self-portrait ǂe none
340     ǂ3 self-portrait ǂh between entry for April 7 and April 19, 1843
