I forget what it stands for, but it is a setting you can put your scanner into when creating a pdf from a scan. It makes the text copy/paste-able. More usefully, I believe it allows one to "search" the pdf.
But basically, an OCR scan allows you to c/p the text into a word.doc or some other application.
FTF, it's a bit dusty now so luckily not my copy. We aim to meet every Saturday for one turn but in reality maybe 2 per month. Then we lost a lot of time over the summer. The German has home-field advantage for his turn and has done a masterful defense maximising building of fortifications. The allied artillery is just getting to enough strength that each corps can hit the toughest defensive hex in their areas hard enough clear them. Of course that's 1 hex at a time.
