Common problems
The survival of anything made of paper depends on the properties of the paper itself, the materials applied to it, and their effect on each other. In contrast to materials such as textiles, where older pieces are usually more fragile than newer ones, the opposite is often true of paper. If stored in a good environment, paper made in Europe from the late medieval period through to the mid-19th century tends to be in good condition. Paper made after the mid-19th century, however, may be affected by the poor quality materials from which it was made. Thus some modern papers only have a lifespan of a few decades.
