Answer 1

Answer:

Need of Preservation and Conservation: When an important, often used book is found in a poor physical condition that restricts its future use and denies the borrower the pleasure of its reading, then the need arises for its preservation and conservation. The need of preservation and conservation are-

a) Decay from Ageing of the Material: Library holdings may begin to deteriorate because of the organic materials from which they are made. Each type of material - paper, glue, plastic, etc. - that goes into the manufacture of a book, recording or optical media has its own combination of physical and chemical properties, and a life span.

b) Damage from Use: The conditions surrounding the processing, storage and use of the materials continuously damage the material.

c) Compendium of Information: Books, journals, newspapers are the sources of information. They reflect social, economic, political and cultural life. They also depict the latest trend on all subjects or topics and, as such, they are a valuable asset of our society.

d) Raw Materials of History: The old reading material constitutes the raw materials of our history and provides background information about an event in history. Nostalgia for such works is another point of consideration.

e) Wide Range of Users: Everyone from a child to an old man, from layman to researchers, turns to information even after hundred years of the publication of the material.

f) Continuous and Future Use: Hard copies of the old as well as new materials are prone to decay. So, to provide continuous and wider access to the collection preservation is a must.

g) Rare Materials: Manuscripts and other materials are of immense value from the cultural and historical point of view and therefore they need to be preserved. Priority should be given to high-value, at-risk materials of national interest. The purpose shall be to serve preventive preservation, as well as security, goals by reducing the handling of the originals.
