Well, you can't really blame them for repeating articles. Just look at all
the paper they need to fill.
For example, if we assume that the WT has been published semi-monthly
for 122 years, the AW for 80 years, the KM for 60 years, and about 100 bound
books published, you come to 184,410 different pages of printing. And I haven't
included the yearbooks, daytexts, calendars, tracts, etc.
This means that they have printed approximately 150 times the volume of the Bible.
So, God's unique words would then equal only 0.67% of their printing.
For an organization that claims to print "Bible based articles", they have certainly
added a lot of their own words to it.
