Pride and Prejudice

Jane Austen

CHAPTER I

It is a truth universally acknowledged, that a single man in possession of a good fortune must be in want of a wife. However little known the feelings or views of such a man may be on his first entering a neighbourhood, this truth is so well fixed in the minds of the surrounding families, that he is considered as the rightful property of some one or other of their daughters.

“My dear Mr. Bennet,” said his lady to him one day, “have you heard that Netherfield Park is let at last?” Mr. Bennet replied that he had not.

“But it is,” returned she; “for Mrs. Long has just been here, and she told me all about it.” Mr. Bennet made no answer. “Do not you want to know who has taken it?” cried his wife impatiently.

“Why, my dear, you must know, Mrs. Long says that Netherfield is taken by a young man of large fortune from the north of England; that he came down on Monday in a chaise and four to see the place, and was so much delighted with it that he agreed with Mr. Morris immediately.”

“Is he married or single?” “Oh! single, my dear, to be sure! A single man of large fortune; four or five thousand a-year. What a fine thing for our girls!”

R Kitap — the most economical way to read

Rent the licence to read, not the book itself. The book opens on the Kibo platform; when the term ends, access closes by itself.

  • Savings of up to 70%
  • Instant access
  • Rich catalogue
  • Protected reading

For organisations

Bulk licensing for schools, municipal libraries and companies: a list set at the start of the term opens under a single contract, and reading is reported in the corporate panel.

Kibo Index

Türkiye's first independent sales and circulation analytics for the publishing sector is coming. Real sales data collected from bookshop tills brings transparency to market trends, category dynamics and weekly bestsellers.

Thirteen digits carry a book's identity. This piece looks at what is inside the barcode and why it does not change with every printing.

Why does record data stay incomplete?

When the same book looks different across channels, the cause is usually not the data but who entered it and when.
