On behalf of a user who asked a question on Commons:
Question about [[s:en:Template:PD-UN]] http://en.wikisource.org/wiki/en:Template:PD-UN and its Chinese and French versions hereto. When Wikisource was a multilingual site accepting all languages, it had so many UN Security Council resolutions posted by various users unaware of UN copyright. As the UN Headquarters is subject to the same USA laws, works published there are copyrighted in the same way as works published in the USA.
Works published in the USA between 1978 and 1 March 1989 without copyright notices and without subsequent copyright registrations are in the public domain in the USA, but should subsequent copyright registrations be validly made, the works become copyrighted. I would like to ask if these works are acceptable here. This is critical as most, if not all, images at [[:Category:Stamps of United Nations]] may be indeed copyrighted.

I thought I ask at the mailinglist, see if anyone can provide an answer...
