If you're looking for a compact set of star maps to bring outside at night, you won't go too far wrong printing these on A3 paper. Might want to print on a B/W printer though. I think they're very good.
Michael,
Well, it's an interesting project for an amateur astronomer to embark on but I'm not too sure about its usefulness to others. For the amateur seeking a free program from which to print maps, there is none better than Cartes du Ciel. It is totally free and has extensive databases and features comparable to commercial programs.
