For permitting photography of the sculptures in their care, and for the interest which they showed, the editors are most grateful to the numerous incumbents and churchwardens throughout the region, particularly at Lythe and Kirklevington; and also Debbie Anderson of the Bowes Museum; Catherine Cullis of the Churches Conservation Trust; Cooper Harding of Thirsk Museum; Elizabeth Hartley of the Yorkshire Museum; Jill Ivy of the Dean and Chapter Library, Durham Cathedral; Andrew Morrison of the English Heritage North Region Store, Helmsley; Philip Philo of Kirkleatham Old Hall Museum; and Leslie Webster of the British Museum.

Sarah Jennings of English Heritage kindly provided photographs and information about three pieces of sculpture newly discovered in the current excavations at Whitby Abbey, and very generously allowed them to be published here.

For providing access to other unpublished information, we would like to thank Chris Chandler of the National Monuments Record, English Heritage; Niall Hammond of County Durham S.M.R.; Graham Lee of North York Moors National Park S.M.R.; Peter Rowe of Tees Archaeology S.M.R.; Robert White of Yorkshire Dales National Park S.M.R.; Bernard Nurse, Librarian of the Society of Antiquaries of London; the staff of the British Library; and Leslie Webster, once again.

The card index compiled by earlier Corpus research assistants, in particular Betty Coatsworth, provided an invaluable basis for the Bibliography.

Karen Atkinson of the Department of Geological Sciences, University of Durham, drew the maps, and other line drawings were kindly provided by Yvonne Beadnell and Ardle Mac Mahon. Tom Middlemass had taken excellent photographs of a number of monuments in the region before his retirement, and the considerable burden of photographic printing was undertaken by Trevor Woods, with additional hand printing by Nan Senior and Mike Smith. Several of the photographs were improved by the digital skills of the Research Associate, Ken Jukes.

As with the previous volume in this series, the final appearance of the book was greatly enhanced by the work of Don Friston. The Bibliography and the Form and Motif Table were set by Ken Jukes.

Other debts are acknowledged in the catalogue, or in the Photographic Acknowledgements. See also the Note on the Catalogue.
