Deacidification is a chemical process that neutralizes acids in paper and deposits an alkaline buffer to slow future deterioration.

Question 3

A library receives a water-damaged book. What is the recommended first step?

Accepted Answer

Place it in a freezer to halt mold growth

Answer

Freezing halts mold growth within 24–48 hours and allows controlled drying later, making it the recommended emergency response.

Question 4

What is the primary purpose of encapsulation in preservation?

Accepted Answer

To protect fragile documents between two sheets of polyester film

Answer

Encapsulation seals a document between two sheets of polyester (Mylar) film to provide physical support and protection without touching the item with adhesive.

Question 5

Which environmental condition poses the greatest risk to photographic materials in a library collection?

Accepted Answer

High relative humidity and temperature fluctuations

Answer

High humidity accelerates chemical decay in photographs and promotes mold, while temperature fluctuations cause physical stress to film layers.
