However, when their owner or the library subscriber wishes to read them they expect the bindings to be in perfectly sound condition. Unlike the majority of products made from leather, bookbindings are expected to last almost indefinitely. That is why when, in the middle of the nineteenth century, it was discovered that large numbers of new bindings were deteriorating rapidly, an explanation was sought. That is also why, over the next century and a half, investigations were made into methods for producing bookbinding leathers with increased resistance to the various agents of deterioration. Care had to be taken, however, to ensure that the materials produced retained the physical characteristics which had made leather the premier choice of bookbinders for hundreds of years. These include ease of paring, easeof moulding, lack of springiness and ability to be tooled.
