It is vital to remember that Tibetan manuscripts are objects of the tangible Cultural Heritage. These objects must be studied in the same way as all other archaeological objects because preserved documents validate memories; the actuality of the object, as opposed to a reproduction or surrogate, provides those living with a link to the past. Preservation of these documents demonstrates recognition of the past and of the things that tell its story. In broader perspective, these documents can aid in the reconstruction of the history of craftsmanship and trade in Tibet. Thus we aim to develop a program for preserving the Mardzong collection and will propose guidelines for conservation procedures to keep the collection in proper condition.
