Preservation Strategies: Mass Deacidification of Paper Collections Study Guide

Understanding Paper Degradation and the Need for Preservation

The term 'slow fires' refers to the rapid combustion of paper in historical books due to extreme heat.

Answer: False

Explanation: The term 'slow fires' is a metaphor for the gradual degradation of paper in old books, primarily caused by the paper's inherent acidity, leading to yellowing and embrittlement over time.
