Homerovah the Almighty spake thusly:
I know they are available at Amazon but are they really still being printed by the WTS. ?
No, of course not. I didn't say they were being printed by the WTB&TS.
The WTB&TS would probably prefer that the titles remained out-of-print and unavailable for all time.
But, in it's wisdom, US Copyright law provides a LIMIT to the copyright term, and once that limit has been met, the publication enters the PUBLIC DOMAIN, and can be reprinted by anyone. The holders of the original copyright no longer control the publication.
Many early Watchtower publications were published without any copyright protection at all. The Golden Age magazine is one. At the time it was being published, the world's end was even closer than it is today, and such secular concepts as copyright protection (which is not mentioned in the scriptures, by the way) were probably seen as unnecessary wastes of effort and ink. Back then, in order to have copyright protection, the publication had to contain somewhere within it a copyright notice. No copy of The Golden Age ever contained such a notice.
Nowadays, with the end of the world so far out of sight, it is necessary for the Faithful and Discreet Slave to avail itself of all the legal protection offered by Satan's governments, and so today virtually every whistle, burp and fart from Bethel is copyrighted to the fullest extent permitted by law, which for published work is 95 years if renewed (and they renew). Oh boy, do they renew! They have to keep their crap out of apostate hands for as long as possible - it is life-giving "water of truth," after all!
