>> But keep in mind, paper does not last forever, the paper they use today >> will probably last for 100 - 150 years, depending on the quality. That is true for certain paper containing acids that was produced in the 19th century. This paper is falling apart because of those acids, but there are methods to rescue it. Older paper is longer-lasting (depending on how it is treated). There are books an documents which are much older and in fine condition. Kind regards, Renate
