Technical implementation

The website and database were developed by Joseph Harper, and additional work was undertaken by Edward Harper. Both work professionally in the IT worlds of software implementation and databases. The logo is by Tom Pollock of Excellent Creative Design.

During the early stages of the project, Anna Burson and Tamsin Rowe undertook some of the preliminary work, and Leofranc Holford-Strevens served as an advisor.
