I found an article «General information about copyrights» where they speak concretely about the copyright notices.Why is it important to place a copyright notice?
«Under the Berne Convention, the absence of a copyright notice does not necessarily lead to the automatic loss of all copyright rights. It does not, however, follow from this that an author can place an incorrect copyright notice without any risk of harm flowing from the notice being incorrect.»
Must I really write «Copyright (C) 2005 Luc Saffre»? Why the «(C)»? Isn't it enough to write «Copyright 2005 Luc Saffre»? Can I write the «(C)» as lowercase «(c)»?
The (C) is not necessary at all if the word «Copyright» is there in full. «A proper copyright notice is (1) the C in a circle symbol (©) or the word "copyright" or the abbreviation "Copr.", (2) the copyright date, and (3) the name of the copyright owner.»
Must I really write every year? «Copyright (C) 1999-2005 Luc Saffre» seems to me more accurate than «Copyright (C) 1999,2000,2001,2002,2003,2004,2005 Luc Saffre»
Seems that this is okay. «Another approach is to put a range of years. For example, if the oldest matter in the work dates from 1991 and if the newest matter dates from 1994, the notice might say copyright 1991 to 1994 and the name of the owner.»
