A message from Scott Moore:

Support the work of myself and other contributors with a one-off tip, or a subscription of £5 a month, or £45 a year.

I've gone out of pocket to put together Civgraph, through subscriptions to newspaper archives, buying a better computer to enable me to produce maps like the 1984 and 1972 council wards maps in digitised formats, and spending on tools to help me develop the website.

With your support, I can cover the costs I incur month to month, work with volunteers to make a greater range of maps available, expand the features on the website, and extend the website beyond maps and boundaries, to include data like election results, Hansard and biographies, all in one place.

All support is appreciated, but if you can't help, don't worry - I release all my maps under an open source license (Creative Commons BY-SA 4.0), and the content of the site will be free forever.
