Old OS 6" maps -- a vast resource

I have mentioned these before, but it's worth reminding people again that we have another vast resource available to us in the old series OS 6" maps -- now around a hundred years old, but with enormous detail on them.  The maps -- covering the whole of the UK -- are available online through the courtesy of the National Library of Scotland.  Nothing to pay, and you don't even have to register as a user.

You can check out the index page here:

Just click on the piece of the grid you would like to examine, and the relevant maps come up on the right of the screen.

I looked up Lydstep this morning, and this is an extract:

This confirmed for me the existence of the place-name "Draught" which had been puzzling me, since it was referred to by the Geological Survey fieldworkers.......

You can look at the 25" maps as well, but the coverage is not complete.
