"It is not surprising therefore that many Muslim heroes in their hour of victory just set libraries to flames. They razed shrines to the ground, burnt books housed in them and killed Brahman, Jain and Buddhist monks who could read them. The narrative of Ikhtiyaruddin Bakhtiyar Khalji’s campaigns in Bihar is full of such exploits... Similarly, only one instance may be given to show how the Indians tried to protect their books from marauding armies. In the Jinabhadra-Sureshwar temple located in the Jaisalmer Fort in Rajasthan, I saw a library of Jain manuscripts called Jain Cyan Bhandar located in a basement, 5 storeys deep down, each storey negotiated with the help of a staircase, and in each floor manuscripts are stacked. The top of the cell is covered with a large stone slab indistinguishable from other slabs of the flooring to delude the invader. Such basement libraries set up for security against vandalism are also found in other places in Rajasthan."
