In addition to what Bruce has said on the very useful set of old maps available at the National Library of Scotland website: http://www.nls.uk/ I would encourage anyone wanting to get the best out of maps like "Thomson's Atlas" to use the "View with Plug-In" option. The first time you select this option, you will bedirected to the website: www.lizardtech.com from where you can download the "browser plug-in". This works fine with all Browsers that I have installed it on, and gives a rather better user interface to the maps ("right-click" on a map to bring up the options). Even if they didn't have all the other Goodies, the NLS site would be worth having for their version of the large-scale OS maps: http://www.nls.uk/maps/os/6inch/index.html which, compared to "old-maps.co.uk", offers (with two alternative user interfaces) a far superior way of interacting with the maps, which gives a pretty good on-screen image for free, and which offers both digital images and printouts for considerably less than Old-Maps.
