For their patient service over many years we would like to thank the staff of the Public Record Office, at Kew and, particularly, Chancery Lane; those at the three county records offices, namely Durham, Tyne Wear Archives Service, Northumberland (at Wideopen, Morpeth and Berwick), and the librarians at Newcastle Central Library.
We would like to thank the latter for their permission to cite manuscripts in their archives:
E.A. Rees, Chief Archivist of Tyne Wear Archives Service; S. Bird, Head of Heritage, Northumberland Record Office; J. Gill, County Archivist, Durham Record Office; and The Court Service, the Crown Court, Durham.
We have appreciated helpful responses and assistance from Newcastle University and Durham University Libraries (the latter in all its branches), as well as our own University of Sunderland; York City Library; the Institute of Historical Research; the British Library; the Bodleian, Oxford; and the National Library of Scotland (the latter two particularly for their efficient and helpful replies to written and electronic enquiries).
For discussions and permission to cite their unpublished PhD theses, we would like to thank Douglas Hay and Peter King.
Academic colleagues who have offered us support and help at various times include Jim Sharpe; Chris Brooks; Clive Emsley; John Styles; Peter King; Maureen Meikle; Tony Barrow; Cindy Burgoyne (whose researches seemed to track alongside our own in a very fruitful way); George Bell; Wilfred Prest; Catherine Crawford; Neil Purvis for the map of the region; as well as numerous speakers who responded to various conference papers.
