*Hi. ) As an admin who regularly works copyrights, I was asked to give feedback here.  precisely points out the problem with this content above. A publication in 2004 is not helpful, even if the letter was written and privately communicated to its recipient decades ago This chart from Cornell gives a basic overview of the situation. Since we are forbidden by policy to take chances in this area, it seems like unless we can verify early enough publication for the content to be public domain the best approach here has already been proposed by  - proper paraphrase and judicious smaller quotes can address the problem. I myself think it would be fine to remove the tag under the circumstances and do that right in the article if it can be done in one go. If more time is needed, or if others prefer the formal route, it can be done in a subpage as described on the template itself. If you go that route, please let me know when it's ready, and I'll go ahead and get it into publication pronto. No reason to have this sit around in limbo longer than necessary. )
