For those with an interest in conservation history, here is a collection of historic correspondence from the 1980s, a period when the best course of action to conserve the Sumatran rhinos in Borneo was being actively discussed. Regrettably, it did not result in the timely intervention which may have made the critical difference to the survival of this species.
