[…] (3) In all jurisdictions where copyright exists, the copyright holder nominally has monopoly on the work for only a fixed term, starting from the date of publication. To know when the copyright will expire, it's essential to know the date from which copyright starts; this is best done explicitly in the copyright statement. I say “nominally”, because another alarming and unilateral trend is to dramatically extend the nominally fixed term, and to strong-arm national governments with terade deals to maximise the copyright term around the world. The effect, as Lawrence Lessig points out: The meaning of this pattern is absolutely clear to those who pay to produce it. The meaning is: No one can do to the Disney Corporation what Walt Disney did to the Brothers Grimm. That though we had a culture where people could take and build upon what went before, that's over. There is no such thing as the public domain in the minds of those who have produced these 11 extensions these last 40 years because now culture is owned. <URL:http://www.oreillynet.com/pub/a/policy/2002/08/15/lessig.html> Or, less poetically, since the term of copyright is only nominally fixed, and in practice just keeps getting extended by newly-lobbied legislation every twenty years or so, the copyright maximalists have de facto instituted “perpetual copyright on the installment plan” <URL:https://en.wikipedia.org/wiki/Perpetual_copyright>. Nevertheless, copyright on works created this century will in principle expire at some date in the future; and to know when that date will be, we need to know when the copyright began. Hence the need for explicit copyright statements saying the date of publication. <URL:http://questioncopyright.org/> -- \ “[T]he great menace to progress is not ignorance but the | `\ illusion of knowledge.” —Daniel J.
