* Putting something in the public domain in the United States offers some freedom from anxiety, but distributing it throughout the world on a network is another matter, even if one has put it in the public domain in the United States. Re foreign laws, very frequently a work can be in the public domain in the United States but protected in other countries. Thus, one must consider all of the places a work may reach, lest one unwittingly become liable to being faced with a suit for copyright infringement, or at least a letter demanding discussion of what one is doing. PETERS reviewed copyright law in the United States. The U.S. Constitution effectively states that Congress has the power to enact copyright laws for two purposes: 1) to encourage the creation and dissemination of intellectual works for the good of society as a whole; and, significantly, 2) to give creators and those who package and disseminate materials the economic rewards that are due them. Congress strives to strike a balance, which at times can become an emotional issue. The United States has never accepted the notion of the natural right of an author so much as it has accepted the notion of the public good and the desirability of incentives to promote it. This state of affairs, however, has created strains on the international level and is the reason for several of the differences in the laws that we have. Today the United States protects almost every kind of work that can be called an expression of an author. The standard for gaining copyright protection is simply originality. This is a low standard and means that a work is not copied from something else, as well as shows a certain minimal amount of authorship. One can also acquire copyright protection for making a new version of preexisting material, provided it manifests some spark of creativity.
