The online Ordnance Survey 1842 maps make use of thousands of tiled images whose file sizes are necessarily quite large. As some windows may require four such tiles to be downloaded at any one time, you will ideally need to have broadband access to the Internet.

If you do not have broadband access, or in any case wish to have speedier access, please send us a self-addressed envelope, containing a blank CD (CD-R). We will then send you a CD with the tiled maps, and instructions for using them with this 'semi-offline' application. Send to

a text file named 'Read Me First'.
