Backpacking/hiking Scotland, need input

[fluter]

Ordnance Survey maps (a national government agency) can be obtained from post offices,local shops,tourist information shops.

For planning purposes, I'd look for the road-atlas version of the OS maps, which used to be called Ordnance Survey Superscale Atlas of Great Britain. I imagine it's still around in some form, mine dates to 1990. It was about 11 pounds, a big spiral bound set of maps for all of Britain.

Searching W.H. Smith, I find this
and this. Can someone in the know give us more info? Edit: Now that I look closely, I see that second link is a 1996 edition.
