1. Web Resources Preservation: According to a report by the US Library of Congress, 44% of the site available on the internet in 1998 had vanished one year later. Web archiving is the process of collecting portions of the World Wide Web and ensuring that the collection is preserved in an archive, such as an archive site, for future researchers, historians, and the public. The Internet Archive is a non-profit digital library with the stated mission of universal access to all knowledge. It offers permanent storage and access to collections of digitized materials, including websites, music, moving images, and books. The Internet Archive was founded by Brewster Kahle in 1996.
2. Film Preservation: The film preservation, or film restoration, movement is an ongoing project among film historians, archivists, museums, cinematheques, and non-profit organizations to rescue decaying film stock and preserve the images contained therein. In the widest sense, its aim is to assure that a movie will continue to exist, as close to its original form as possible. Films are highly inflammable. So, necessary action should be taken so that in no case it comes in contact with high temperature.
Like print, digital media, and film, the paintings, photographs, phonograph also demand some special preservation techniques.
3. Let Us Sum Up: Prevention of deterioration measures significantly extends the usual life of all types of documents and must need to be implemented. In doing so, the person concerned should work with curators, recommending officers, and other preservation staff to make decisions about binding, housing, and related matters.
Remedies against environmental damage of reading material include shielding from sunlight, air conditioning and such others in all walk of the material such as in store, on display, or in transit.
The storage areas should be clean and clutter, dust, dirt etc should not be allowed to accumulate within the storage areas. When the books are in the shelf, safe storage or use of proper storage cabinet by way of keeping the valuable reading material in box and keeping documents in between metal supporters provide protection against mechanical damage. It also helps the document in being free from dust, dirt and direct exposure of light.
Insects, mold, rodents are dangerous for a document. Generally pests are attached by clutter and the food remnants. So, eating, drinking etc should be prohibited in a place where collections are kept. During cleanliness all necessary measures should be taken so that cleanliness itself does not damage the fragile materials. In the library, disaster recovery plan should be put in place.
Repairing of document includes use of adhesive, repairing tears, etc. Tears in leaves can be carefully aligned and repaired with the strips of Japanese paper and a starch paste or other suitable adhesive that bears the quality of good conservative. This process should be followed by binding. Generally library binding is considered good for many kinds of documents. The special collection should be treated specially.
Because of the big volume of library material having chances of deteriorating widely, diverse material and methods for preserving them involves considerable cost. It will be therefore, if the libraries are turning to cooperative arrangements for preservation.
