Rare first edition books by famous names such as Isaac Newton and Jane Austen are to go under the hammer at an auction in Dorset.
Pride and Prejudice is expected to go for £12,000
Rare copies of Charles Dickens' novels and limited prints of Chaucer's Canterbury Tales are also on sale.
The collection is expected to raise up to £500,000 when it is auctioned at Duke's of Dorchester on 8 March.
The sale features two major collections, including the Newton library, which was started in 1920.
Guy Schwinge, of Duke's auctioneers, said collector Sir Henry Newton was "lucky to be buying at a time when the supply of rare books was abundant".
A prized copy of Darwin's The Origin of the Species, printed in 1859, is expected to sell for up to £50,000.
Meanwhile, a first edition of Austen's Pride and Prejudice, recently voted by book-lovers as Britain's favourite read, is estimated at £12,000.
Other books in the collection include a rare copy of Dickens' Great Expectations and first editions of Robinson Crusoe and Gulliver's Travels.
