Seshat is investigating big questions which need high quality data. We rely upon large numbers of people cooperating to collect and improve our data. If you spot anything that is wrong, or you know of evidence that we do not cite which contradicts our data, please let us know. We are always grateful and happy to acknowledge the sources of new evidence and don't mind at all if it contradicts our existing data. As our site is still being developed, please also email us at: firstname.lastname@example.org and let us know which polity/ies you have left comments or suggestions on to ensure that we receive it.
