We keep all editions of these now, since we notices things like "area 59"
or whatever it is, is no longer noted on newer editions. Also some nuclear
testing and aeronautical testing grounds, say in Nevada or Arizona, are no
longer marked as in previous editions. A reader pointed this out to us
years ago, and it made the case for retaining back issues of these maps.
