Copyright protection means that using a copyrighted work is lawful only if we get authorization from the copyright owner. As explained by WIPO on its website in the section "International Protection of Copyright and Neighbouring Rights", the authorizations granted by the copyright owner can be: "The right to copy or otherwise reproduce any kind of work; the right to distribute copies to the public; the right to rent copies of at least certain categories of works (such as computer programs and audiovisual works); the right to make sound recordings of the performances of literary and musical works; the right to perform in public, particularly musical, dramatic or audiovisual works; the right to communicate to the public by cable or otherwise the performances of such works and, particularly, to broadcast, by radio, television or other wireless means, any kind of work; the right to translate literary works; the right to rent, particularly, audiovisual works, works embodied in phonograms and computer programs; the right to adapt any kind of work and particularly the right to make audiovisual works thereof." Under some national laws, some of these rights - which together are referred to as "economic rights" - are not exclusive rights of authorization but, in some specific cases, merely rights to remuneration. In addition to economic rights, authors - whether or not they own the economic rights - enjoy "moral rights" on the basis of which authors have the right to claim their authorship and require that their names be indicated on the copies of the work and in connection with other uses, and they have the right to oppose the mutilation or deformation of their works. = Shrinking of public domain Michael Hart created Project Gutenberg in July 1971 to make electronic versions of literary works and disseminate them for free. In 2009, Project Gutenberg has had tens of thousands of downloads every day. As recalled by Michael in January 2009, "I knew [in July 1971] that the future of computing, and the internet, was going to be... 'The Information Age.' That was also the day I said we would be able to carry quite literally the entire Library of Congress in one hand and the system would certainly make it illegal... too much power to leave in the hands of the masses." As defined by Project Gutenberg, "public domain is the set of cultural works that are free of copyright, and belong to everyone equally", i.e. for books, the ones that can be digitized and released on the internet for free. But the task of Project Gutenberg hasn't be made any easier by the increasing restrictions to public domain. In former times, 50% of works belonged to public domain, and could be freely used by everybody. A much tougher legislation was set in place over the centuries, step by step, especially during the 20th century, despite our so-called "information society". In 2100, 99% of works might be governed by copyright, with a meager 1% for public domain.
