No change as to number of books. I have been a reader all my life with a love affair with books. If you count in all the WTS books make that 1000 plus then. I have found that people either are readers or they aren't whether they are JWs or not. I have met many JWs that don't read the WTS publications let alone a "worldly" book. Then I have met JWs that read a great deal besides the WTS publications. And that works with people who aren't JWs. My workmates are not JWs and they don't read any more than some of the JWs I know.
