The updated versions of the Copyright Act can be found below http://www.copyright.gov/title17/
Below, I found text for disc, records, or tapes that said, "Under the 1909 law, courts have also held that the notice of copyright on a derivative work ordinarily need not include the dates or other information pertaining to the earlier works incorporated in it. This principle is specifically preserved in the present copyright law. Thus, if the copy (or the record, disc, or tape) " http://www.copyright.gov/circs/circ22.html#derivative I think the multiple dates are related more towards figuring out if it is a derivative work or a revised version for the purpose of registering it to the government. http://www.copyright.gov/circs/circ61.pdf Sorry, to high-jack the thread with this. The gphpedit author wants to place copyright and license notices in the files that he is copying from other projects to make it . He says he got the authorization from the previous authors to do so and that the gtkscintilla project is not being worked on anymore. I believe it is neither lawful nor has any point to do so anyhow, because it would be probably placing the wrong copyright. What gets me is how does anyone know when the true copyright date is? -- Nicodemo Alvaro
