THE ART OF PRESERVATION
            AND CONSERVATION


            To protect its Records, TCA follows good
            housekeeping practices.

            Records face many threats, including
            dampness, weather, insects, damaging
            fasteners or acid from the paper or containers.
            Dust, pins, damaging fasteners are removed
            and acidic storage materials like boxes and file
            folders are replaced with materials of known
            archival quality.


            The greatest threat to the Records is from
            natural degeneration. They are housed in a
            dust-free environment in climate-controlled
            repositories to ensure consistent temperature
            and humidity. Since frequent handling of
            Records increases the danger of damage, only
            digitised versions are used for dissemination.

            Each Record is different and so the
            conservation, restoration and preservation
            treatment followed varies. Before any
            conservation procedures are carried out, the
            Records are either scanned or photographed
            as a precautionary measure.


            As is the practice worldwide, TCA only uses
            reversible methods for conservation. This
            means that processes can be undone at
            a future date with no harm to the Record.
            Documents undergo the process of ink fixation,
            followed by deacidification. Thereafter, they
            are lined using acid-free materials. The type of
            lining varies depending on the document, while
            most are given a double-sided lining of acid-
            free Japanese tissue paper, others are only
            given guiding around the edges with a backing
            using appropriate material.


            Although the TCA staff has been trained in
            conservation, the services of independent
            conservators and specialists from
            professional organisations like the Indian
            National Trust for Art and Cultural Heritage
            (INTACH) are also consulted.
