Documenting the preservation of these fragile pieces is a core practice for serious archivists. | Condition ImpactAcidic paper becomes brittle over time, making corner dings and surface creases much more likely during handling. Storing these cards in inert, PVC-free holders is necessary to halt the chemical breakdown of the original wood pulp. |
