I would like to thank all of those people and organisations whose insights and copyrighted work provided the foundations for this project. The images appearing on this site are the result of many hours of hard work. It is therefore immensely kind of people to allow me to reproduce their pictures here.
Please note that although a copyright holder may have given permission to use an image, it in no way means that a copyright holder endorses the findings of the project.
