What is the situation when you want to include information which is essentially in the public domain (e.g. a historical list of the Governors- General of NZ) but where all the convenient sources have their own copyright notices? Are they in effect copyrighting the information (which I would consider to be in the public domain) or just their presentation of it?
Facts cannot be copyrighted, only particular presentations can. Even if someone claims copyright on a very basic factual list, you can safely ignore it.
