[ceayo]

Without books, what books are they going to read?

[SauntSolaire]

E-books supposedly, since the parent explicitly specified paper books.

[bentley]

Other books that are checked out often enough to justify the library keeping them.

[LaGrange]

Other paper books. Or the same books but electronic or reprinted when the demand is higher. Just not the exact same pieces of highly fetishized dead wood.
