Reading "older publications" published by the Watchtower is actually encouraged.
It certainly used to be Atlantis, but you will find nothing like the following in any Watchtower written in this century, the irony of this becoming old light is quite striking;
“Those who really are growing in maturity find that familiarity with basic theocratic publications is a tremendous aid ... Their zeal for knowledge may even prompt them to dig back into things that were published long before they came into the truth, expanding and deepening their understanding, and ever growing in Christian maturity. Do you dig out older publications to expand and deepen your knowledge … Have you really studied these earlier publications? ... How is your background of knowledge? ... Studying them is not a chore, but a pleasure when your interest is not in the number of pages you are to read, but rather in the knowledge that you will get, ... Never think: “Oh, I know most of that.” For you will find, indeed, that you do not … And once you have completed your study of them you can then look to even older publications. ... studying earlier publications and digging back through previous issues of The Watchtower ... There is much in the way of spiritual riches and aids toward mature knowledge in these earlier publications, and their study is most certainly worth your time. By checking back through the Society’s earlier publications you will … rejoice to see your understanding continue to grow.” (Watchtower, May 15, 1957, pages 313, 314 and 315).
