The letters which are printed in these volumes have been selected from the correspondence of the family of Hattcn which forms part of the Hatton-Finch papers preserved in the British Museum. These papers, contained in forty-nine volumes, comprise—as their title indicates—the general correspondence and papers of the connected families of Hatton, Viscounts Hatton, and Finch, Earls of Nottingham and Winchilsea. They extend over the years 1514–1779; but the larger portion concerns the Hattons, and of those which relate to the Finches the greater number are political papers of the second Earl of Nottingham. The collection was purchased by the Trustees of the British Museum in 1874, and now bears the numbers, Additional MSS. 29,548–29,596.
