"I am astonished," said Miss Bingley, "that my father should have left so small a collection of books. – What a delightful library you have at Pemberley, Mr. Darcy!"

– Jane Austen

Pride and Prejudice, Chapter 8. While Elizabeth is visiting the Bingleys to see her ill sister Jane, there is a discussion on reading, in which Caroline Bingley compliments Mr. Darcy on his excellent library at Pemberley. A love of books is something which Darcy and Elizabeth share, and one of the things that draws them closer over time. Of course Caroline has little interest in reading, but pretends she does in order to gain the attention of Darcy.
