As someone who grew up on a small island with 700 people on it, with one tiny library that I could borrow unlimited amount of comic books from (a lot of Tintin and Asterix :) ), that does sound strange.

I assume they meant 1 to purchase, not borrow or read.

Aha, "libraries" instantly made me think about borrowing, not buying. But I suppose there are libraries out there where you can buy books too.
