There is also the wonderful Cheshire Tithe Maps site, where you can compare two maps side by side:
Cheshire Twin MapsUse the drop-down tab selector to Jump to Marple and select the maps you want to compare in each window then move around, zoom in and out etc. See who owned different plots of land and see how things have changed over the years.
Fascinating stuff and you can lose hours of time on there!
I'm not sure how well it will work on small devices.
