I buy paperbacks simply because I need to maximise shelf space :-) I
don't mind them getting a bit scruffy, but having the pages fall out
definitely spoils one's enjoyment.

I bought a Kindle to maximise shelf space.

A waste paper basket does the same, or putting them in the pub library
where they can be swapped for another.
I got fed up with returning to reread a book after 5 years or so and
finding old pages that had yellowed and just felt tatty. If it is good
enough to reread then obtaining a newer copy that hasnt deteriorated isnt
usually that difficult.
