This is Interesting, and I wonder if it's part of a Larger Campaign to Remove WT Archived info from the Web.
I have used http://www.a2z.org/wtarchive/archive.htm several times in the Past, and Recently I noticed that all Content Links are Dead.
There is Still the Trusty : http://wtarchive.svhelden.info/ up and well though.
I downloaded all publications from this Site, and Converted them to OCR Files, which Means I can Search 1879-1963 Publications the same way I can Search Publications in the WT Library.. Type a Phrase or Scripture, and I get a List of all Mentions.
Let me know if I can Retrieve any Particular info for anyone.
