Copyright A Symbol

How could we wrap a discussion on copyright without discussing the all-important symbol which defines copyright? A symbol which is a warning to plagiarists to stay away from the content their eyes are on. Copyright is denoted by a simple symbol which is an encircled capital C. Some countries have got rid of this symbol altogether but in most part of the world, it continues to be significant. There is an international convention, Universal Copyright Convention adopted in Geneva in 1952, which recognizes this symbol.
