We would like to thank the Royal Commission for the Exhibition of 1851 for their generous support towards the purchase of the equipment used in imaging our historical collections, including the Clayton Herbarium, and The Mercers' Company for supporting the development and completion of this project.
We are most grateful for the help and assistance of a number of people in making the images of these Clayton specimens available in this form. Jim Reveal (University of Maryland) first had the idea of digitising images of this collection some ten years ago but costs have proved prohibitive until now. His work on the collection, and for the Linnaean Plant Name Typification Project, has been particularly valuable and with Norlyn Bodkin (James Madison University), he searched for the Clayton specimens allowing their curation as a separate collection. Fred Barrie and Nick Turland (both now at Missouri Botanical Garden) contributed extensively via their work on the Linnaean Typification Project, and we are grateful for grant support from NSF, the Leverhulme Trust and the Linnean Society of London, which has allowed the necessary research to be undertaken over a number of years. We would also like to thank St Thomas' Network, Dudley, for both their technical support and providing volunteer help.
