Lord Spencer obtained the library at a cheap rate. The same noble collector offered the Duke di Cassano Serra £500 for two books, viz., the Juvenal of Ulric Han, and the Horace of Arnaldus de Bruxella, Naples, 1474, but the offer was not accepted. In 1820 Lord Spencer bought the whole collection.
The Duke of Devonshire purchased the valuable library of Dr. Thomas Dampier, Bishop of Ely, for nearly £10,000 after the bishop’s death in 1812. Dr. Dibdin has printed in his “Reminiscences” (vol. i. p. 363) a list of prices at which Dr. Dampier valued the various classes of books in his library.
Little idea of the prices of books can be obtained from the amounts given for a whole library, but as in future chapters particulars will be printed of the great libraries that have been disposed of by auction, it seemed well to mention here a few instances of libraries that have been sold entire. The greatest of these is the magnificent library of Earl Spencer, which was sold in 1892 to Mrs. Rylands, and has been transferred from Althorpe to Manchester. The exact amount paid for this library has not been announced, but it is supposed to have been about a quarter of a million pounds.
