A to Z copyright trick
« on: Sunday 15 October 17 15:16 BST (UK) »
I know that the publishers of the A to Z maps add fictitious streets to their maps, in order to dissuade/detect people illegally copying their work.  Can anyone remind me of the name given to this little "trick"?

James Stott c1775-1850. James was born in Yorkshire but where? He was a stonemason and married Elizabeth Archer (nee Nicholson) in 1794 at Ripon. They lived thereafter in Masham. If anyone has any suggestions or leads as to his birthplace I would be interested to know. I have searched for it for years without success. Thank you.

Also known as a "tell".

Used in sensitive documents that get circulated to a restricted list of people .... each copy will be slightly different - usually an extra space between words, or a misplaced comma.  Then if the document turns up somewhere it shouldn't it is easy to work out who leaked it.
