The wood from which paper is made is mainly cellulose fibers and lignin, which fills the voids between them. Lignin gives paper its yellow tint, so it is desirable to remove it during the manufacturing process. Previous technologies did not allow doing this efficiently, which is why the paper turned out to be yellowish and loose. Over time, lignin decomposes to form odorous substances, including benzaldehyde with the smell of bitter almonds. And among the products of cellulose degradation there is furfural with the smell of rye bread. There is almost no lignin in modern paper, so our books, when they are old, will smell differently than the ancient ones.
