PETERS next reviewed the economics of copyright holding. Simply, economic rights are the rights to control the reproduction of a work in any form. They belong to the author, or in the case of a work made for hire, the employer. The second right, which is critical to conversion, is the right to change a work. The right to make new versions is perhaps one of the most significant rights of authors, particularly in an electronic world. The third right is the right to publish the work and the right to disseminate it, something that everyone who deals in an electronic medium needs to know. The basic rule is if a copy is sold, all rights of distribution are extinguished with the sale of that copy. The key is that it must be sold. A number of companies overcome this obstacle by leasing or renting their product. These companies argue that if the material is rented or leased and not sold, they control the uses of a work. The fourth right, and one very important in a digital world, is a right of public performance, which means the right to show the work sequentially. For example, copyright owners control the showing of a CD-ROM product in a public place such as a public library. The reverse side of public performance is something called the right of public display. Moral rights also exist, which at the federal level apply only to very limited visual works of art, but in theory may apply under contract and other principles. Moral rights may include the right of an author to have his or her name on a work, the right of attribution, and the right to object to distortion or mutilation--the right of integrity. The way copyright law is worded gives much latitude to activities such as preservation; to use of material for scholarly and research purposes when the user does not make multiple copies; and to the generation of facsimile copies of unpublished works by libraries for themselves and other libraries. But the law does not allow anyone to become the distributor of the product for the entire world. In today's electronic environment, publishers are extremely concerned that the entire world is networked and can obtain the information desired from a single copy in a single library. Hence, if there is to be only one sale, which publishers may choose to live with, they will obtain their money in other ways, for example, from access and use. Hence, the development of site licenses and other kinds of agreements to cover what publishers believe they should be compensated for. Any solution that the United States takes today has to consider the international arena.
