If you are reading about Roman Purbeck Stone, please read on.
The public version of Roman Purbeck Stone is a copy of a fuller version which I keep for my own use. For publication, I have to omit (a) some pictures, for reasons of copyright, or sometimes because of their mere size; (b) some personal data about individuals; (c) some sensitive information about particular archaeological sites. This is the reason that some links in the public database don't work.
Please contact me if you would like to know more about a particular item than I can show here.
