In 1609 he purchased the library of John, Lord Lumley, a great part of which had previously belonged to his father-in-law, Henry Fitz-Alan, Earl of Arundel, and another large proportion to Thomas Cranmer, Archbishop of Canterbury. He also acquired a number of books which had belonged to a Welshman, John Maurice or Morris. On the Prince's death his library became the property of James I., and it was added to the existing Royal Library, then under the care of Patrick Young.
