Physical Description:
Other Physical Details - Plastic-Treated:
All the National Geographic Societys plasticized items are printed directly on "texoprint" (i.e., a latex coated/impregnated Kraft paper from Kimberly Clark). For these and analogous items, the phrase plastic-treated is preferred to plastic as "other physical details" information.
The coded physical description field (tag 007) for these items is coded as paper rather than plastic.
