Burning and disposing of old books is exactly what the Society wants, so that there is no paper trial. I remember years ago when I served in the congregation, we received a letter from the Society. The letter went on to brag of the great work the Society was doing, and all the new offices and printing facilities and bethel homes bing constructed worldwide and that these places needed theocratic books for their libraries and the Society was reaching out to the rank and file to supply these needed books. They SPECIFICALLY asked for Russell, Rutherford books and magazines.
Some years later I was talking to a former betheilite elder and he told me the Society received tons of boxes of these books and they burned them all.
