To follow up (even more emphatically) Bob's reply: - `Copyright _year1_, _year2_, _year3_ _copyright-holder_` + `Copyright (C) _year1_, _year2_, _year3_ _copyright-holder_`
The ASCII (C) is neither forbidden nor required; it is irrelevant, legally. What counts is the English word "Copyright" (or the c-in-a-circle character, but that should not be used since it can cause unnecessary encoding hassles). It is possible that courts might recognize ASCII "(C)" as an alternative representation of c-in-a-circle, but to the best of my knowledge this has never been tested, so best to avoid it, since there is no loss in doing so. I looked this up at the Library of Congress web site years ago. Copyright notices without a "(C)" are widespread, and totally fine. And shorter. I don't think we should imply that "(C)" is meaningful. IMHO. -k P.S. The maintainers file is written as it is because every single (semantic) change of words must be approved by rms. Therefore when I proposed or passed on changes I did my utmost to minimize the changes he had to look at. That often meant ending up with wording that is different than it would have been had it been written from scratch. --
