The present world is changing from the industrial world to the information world. It requires fast, accurate, organized and reliable information. People are beginning to know the value of information. A large amount of information is being generated every second all around the world. The information has become a raw material and a dominating factor in the process of decision making and execution. Information is and will be a primordial need for each individual in this world. Information is regarded as &;Lifeblood of society&; and a vital resource for national development. On the other hand there are libraries with rare collections which are the treasures of local heritage. They reflect the heritage and culture of the society. The information in these libraries is in a variety of forms such as palm leaves, manuscripts, printed books, etc. Preservation requirements of these library holdings are obviously different from those of libraries established during the recent past.
