They don't make paper for books now that will last:
paperbacks, tons of them and best seller after best seller. Even the hardbacks don't use good paper. Read em and pass em on. No one has libraries with books floor to ceiling, bound in leather or good fabric.
No one keeps their books for ever and ever.
I have some older books from the 1910s and they used a finer, smoother paper that was more durable. Todays paper is porous and disintegrates easily.
The magazine I work for uses very high quality paper and our photos really show off. People archive the magazine for decades. Not a Family Circle, House Beautiful or Woman's Day quality paper... it is really noticeable, but then we appeal to higher end, better photography...
