Deterioration of library materials caused by internal/ external causes like temperature and humidity extremes, light, air born pollutant,  molds and pests is usually gradual and cumulative and is always irreversible.

Some of the library materials deteriorate more quickly than others because they are made from different materials that are inherently unstable such as acidic paper.

Disasters such as floods, fires, building problems such as leaking roofs, may cause immediate deterioration.  The materials in which the library archive collection are made of namely paper, parchment,palm leaves, birch bark leather and adhesive use of bookbinding also cause deterioration of library materials. 

Mans negligence such as accumulation of dust and dirt from poor or careless housekeeping practices, poor ventilation, introduction of foodstuff in to storage and exhibit areas favors the growth of proliferation of insects.

Deterioration of library materials caused by regular components, for example, temperature and dampness extremes, light, air-borne toxins, shape, and vermin, is generally steady and aggregate and is constantly irreversible.

Some library materials fall apart more rapidly than others since they are produced using materials that are intrinsically unstable, for example, acidic paper. Catastrophic events, for example, surges or flames, and building issues, for example, spilling rooftops or useless HVAC frameworks, may cause more prompt weakening.

The materials of which library and document accumulations are made, to be specific paper, material, palm leaves, birch bark, leather and cement utilized as a part of bookbinding, are powerless to two principal types of decay.
