Thanks, but unfortunately those newspapers don't cover the areas I need. In case they help someone else, the list is
New Jersey Advocate| |Rahway Daily Record and New Jersey Advocate| |Rahway News Herald| |Rahway News Record| |Rahway Progress| |The National Democrat| |The Rahway Advocate| |The Rahway Realty| |The Rahway Record| |The Weekly Advocate And Times|
The "Red Bank Register" archives are also online: http://220.127.116.11/search.htm
If anyone finds Newark and/or Harrison online, I'd be forever grateful.
