This isn’t anything new. They have been getting rid of certain publications and books in Kingdom Hall libraries over the years.. I figured that most of what was there was a showcase of sorts with nobody really reading it - but I thought they would be proud of it at least.
Back in the day I donated a very old book that a lady in the neighborhood gave me. One day I looked and presto it disappeared along with something else I had donated.
The Witness religion is completely rewriting and sanitizing their history IMO. It wants NO evidence of anything said or taught in the past.
