Facts on copyright

• It appears publishers, rather than authors, were the first to seek restrictions on copying printed works. Given that publishers now obtain the copyright from the authors as a condition of mass reproduction of a work, one of the criticisms of the current system is that it benefits publishers more than it does authors. This is a chief argument of the proponents of peer-to-peer file sharing systems. It set out a rabbinical curse on anyone who copied the contents.
• Copyright may subsist in a wide range of creative or artistic forms or "works". These include poems, plays, and other literary works, movies, choreographic works (dances, ballets, etc.), musical compositions, audio recordings, paintings, drawings, sculptures, photographs, software, radio and television broadcasts of live and other performances, and in some jurisdictions industrial designs.
• With the exception of a small number of countries which still require notices to be on works, this requirement is generally optional except for works which were originally created before the particular country became a member of the Berne Convention (the members of which are collectively known as the Berne Union).
