手再干净也含有油脂、汗渍、灰尘和霉菌等污染物，因此拿取书画要带手套，观赏时人与书画保持1.5米左右的距离，以免讲话时唾液飞溅到书画上。秋高气爽的季节，可以将收藏的书画取出掸尘、晾放，让吸收的水分挥发。

纸质文物的保护难度很大，收藏不当，会损坏藏品的品相。古人收藏书籍要用函套，字画用精制的画匣。制作画匣的材料要精选，防止木材中的油性物污染纸张，古代的木画匣不但选材讲究（常用樟木），而且是多层材料复合，外层是樟木，中间为楠木，里层用上等丝绸，画还要用布套包裹。

The protection of paper-based cultural relics is very difficult. Improper collection will damage the appearance of the collection. The ancients used letter cover to collect books, and refined painting boxes were used for calligraphy and painting. The materials for making picture boxes should be carefully selected to prevent oil in the wood from polluting the paper. The ancient wooden painting boxes not only selected materials carefully (commonly used camphor wood), but also were made of multi-layer materials. The outer layer was camphor wood, the middle was nanmu, the innermost layer was made of superior silk, and the paintings were wrapped in cloth.
