Hello, English Heritage in the UK would like to publish the frontispiece image from 'The Buxton diamonds, or, Grateful Ellen : for the amusement and instruction of children' in a new printed guidebook to Peveril Castle. The book is out of copyright and I think the digital rights have been waived by the University of California Libraries and the digitization sponser, Microsoft. Therefore I think we are OK to publish the image, but I wanted to check what credit line we should include in the guidebook.
