Congregations get an annual letter that tells what can be ordered for literature (it's mainly a list of audio CDs/DVDs for the deaf), but this time it included publications that will be discontinued, and this included the Isaiah's Prophecy book and the Reasoning book, and I think I saw the Draw Close to Jehovah book. I meant to take a picture of the letter but forgot. The branch is only going to give what they have on stock, when that stock depletes that's it, you won't be able to order those publications anymore.
This is in Canada so I don't know if this is worldwide.
