Hello
I just finished writing the code for this Watermills of Sheffield page, it's an interactive map showing all the locations of the watermills listed in the book 'The Water-Mills of Sheffield' by W.T. Miller published in 1947. Tap on a mill for its name, and tap on the name for the description from the book.

I've written it for use on a mobile phone, for when you are out and about, and on this the GPS can be used to show your location. It will also work with a desktop PC.
Thanks
Karl.
