Copying

See ENGRAVING, PHOTOGRAPHY, LITHOGRAPHY. Copyright. Right of the owner of a literary publication to prevent all others from copying it: it rests upon statute. In the U. S., the term for which a copyright may be obtained is 28 years, with a right of renewal for 14 years in most cases. International copyright, though long existent between other countries, was not granted by U. S. till 1891, and then imperfectly.
