The task of keeping books, manuscripts, and other materials in usable condition is made more difficult by the very nature of modern paper.
Paper made before 1850 was produced using rags and animal glue. Rag paper sized with animal glue is still flexible after more than 150 years, as can be seen from this book.

Paper produced after 1850, however, is most commonly manufactured using wood pulp (which contains lignin) and alum-rosin sizing. The use of wood pulp or alum and rosin results in highly acidic paper, which becomes dark-colored and brittle in a very short period of time.
This book, published in 1965, has already become embrittled along the page edges.
In a few years, deterioration of the paper will become so severe that pages crumble and break with each turn.
The book was published in Germany about 1945.
