The printing figure in the w public ed of 42,162,000 is the total for the month. The study ed is included. It breaks down to about:
Public=28 million
study=14 million
The way it is worded in the public ed is misleading in my opinion. It says "each issue" which makes you think its for the public ed only, but actually its the total monthly printing for The Watchtower all together-all editions. They are all the same magazine- "The Watchtower".
Expect the printing total for the 2012 SY for w & g to pass one billion copies printed again.
