A copyright notice, either as symbol or phrase, informs users of the underlying claim to copyright ownership in a published work.
Copyright law is different from country to country, and a copyright notice is required in about 20 countries for a work to be protected under copyright. Before 1978 all published works in the US had to contain a copyright notice, typically the © symbol followed by the publication date and copyright owner's name, to be protected by copyright. Until 1989 all such published works in the USA required either a copyright notice or a registration filing within five years of publication. This is no longer the case and use of a copyright notice is now optional in the US, since the adoption of the Berne Convention Implementation Act of 1988.

Famous quotes containing the word notice:
“Is not a patron, my lord, one who looks with unconcern on a man struggling for life in the water, and, when he has reached ground, encumbers him with help? The notice which you have been pleased to take of my labours, had it been early, had been kind; but it has been delayed till I am indifferent, and cannot enjoy it; till I am solitary, and cannot impart it; till I am known, and do not want it.”
—Samuel Johnson (1709–1784)
