History of the Harleian library

The Harleian library was founded in October 1704, when Robert Harley (1661–1724) purchased more than 600 manuscripts from the collection of the antiquary Sir Simonds d’Ewes (1602–1650). In 1711, Harley was elevated to the peerage as 1st Earl of Oxford and Mortimer, from which date his son, Edward Harley (1689–1741), was most active in augmenting the collection. The 1710s saw further groups of important English manuscripts enter the library, and from about 1717 the Harleys also began using overseas agents to make en bloc purchases of manuscripts from Continental Europe, especially France, Germany and Italy. Numerous important British and foreign collections were auctioned in London in the 1720s, allowing further individual acquisitions. Edward Harley, 2nd Earl of Oxford and Mortimer, maintained a wide circle of friends, among them the writer Jonathan Swift (1667–1745) and poet Alexander Pope (1688–1744).

A prominent role in the formation and expansion of the library was played by the scholar Humfrey Wanley (1672–1726). Wanley, one of the original members of the Society of Antiquaries in 1707 (refounded in 1717), became library-keeper to the Harleys in 1708. His diary (Lansdowne MSS 771–772) and letters are an important resource for describing the acquisition of individual manuscripts, and for understanding the growth of the collection as a whole.

Edward Harley bequeathed the library to his widow, Henrietta Cavendish Harley (née Holles), countess of Oxford and Mortimer (1694–1755), during her lifetime, and thereafter to their daughter, Margaret Cavendish Bentinck, duchess of Portland (1715–1785). In 1753, the manuscripts were sold by the Countess and the Duchess to the nation for £10,000 (a fraction of their contemporary value) under the Act of Parliament that also established the British Museum.
