Today biological deteriorative agents had a big role in deterioration of books as it was in the past. The human has been aware of the damage in books caused by the factors like temperature, humidity, dust and light since ancient times. Therefore, the books and documents have been conserved by different cultures at different ages with varied treatments. The ink and paper was treated during the production of the book to prevent biological deteriorations and also enviromental factors in the libraries had been regulated and improved. The care, conservation and restoration of the books accepted as a special field today was a function of a library in the past. With the advancement of science, modern methods have replaced traditional methods and mass treatments such as fumigation, anoxic system and low temperature treatment was carried out. But today it is known that the most important factor in the protection of Manuscripts as a library material like other cultural heritage materials is preventive conservation. In this paper with the investigation of modern and traditional methods, it has been concluded that the tradiotional techniques and materials with improvements can be used and implemented in conservation of manuscripts.
