A collection of 500 pre-1800 books were recently relocated to a permanent location in Library and Archives Canada’s rare books vault. The vault is equipped with optimal environmental conditions to ensure this special collection is properly preserved for generations to come. Prior to being transferred to Library and Archives Canada, the books were owned by the Library of Parliament. Most of this collection consists of books published in England or France, and many are multi-volume sets. The subject matter ranges from geography and history to theatre and essays.
About the Collection
The majority of the books are 18th-century hand bindings bound in full or partial leather. The collection also comprises some books made of paper, cloth or parchment. The books are decorated with intricate gold titling and tooling and are often accented with unique and stunning marbled papers, commonly used as the endpapers.
The condition of the books
Before being added to the Rare Book Collection, factors such as moisture, temperature, light and dust contributed to the deterioration of many of the books. Although some books are in excellent condition, with the binding structures and text blocks intact, many are damaged and show signs of damage. Some items have suffered from water and fire damage, or contain traces of a pest infestation, while others are weakened and damaged due to centuries of physical use.
Red rot and leather deterioration
A large percentage of the collection (approximately 90%) suffers from various levels of leather deterioration. In some extreme cases, the type of damage is referred to by conservators as red rot. The deterioration of leather is a common issue in leather from this period as the tannins used in the manufacturing process contain chemicals that, over time, and in the presence of oxygen, undergo a chemical change that breaks down the leather molecules. This causes the leather to weaken, flake and powder.
