Copyright

...is a form of protection provided by the laws of the United States (title 17, U. S. Code) to the authors of “original works of authorship,” including literary, dramatic, musical, artistic, and certain other intellectual works. This protection is available to both published and unpublished works. Section 106 of the 1976 Copyright Act generally gives the owner of copyright the exclusive right to do and to authorize others to do the following:

• To reproduce the work in copies or phonorecords;
• To prepare derivative works based upon the work;
• To distribute copies or phonorecords of the work to the public, by sale or
other transfer of ownership, or by rental, lease, or lending;
• To perform the work publicly, in the case of literary, musical, dramatic, and choreographic works, pantomimes, and motion pictures and other audiovisual works;
• To display the work publicly, in the case of literary, musical, dramatic, and
choreographic works, pantomimes, and pictorial, graphic, or sculptural
works, including the individual images of a motion picture or other audiovisual work; and
• In the case of sound recordings,* to perform the work publicly by means of a digital audio transmission. In addition, certain authors of works of visual art have the rights of attribution and integrity as described in section 106A of the 1976 Copyright Act. For further information, see Circular 40, Copyright Registration for Works of the Visual Arts.

__________________________________________________ __________________________

It is illegal for anyone to violate any of the rights provided by the copyright
law to the owner of copyright. These rights, however, are not unlimited in
scope. Sections 107 through 121 of the 1976 Copyright Act establish limitations
on these rights. In some cases, these limitations are specified exemptions from
copyright liability. One major limitation is the doctrine of “fair use,” which
is given a statutory basis in section 107 of the 1976 Copyright Act. In other
instances, the limitation takes the form of a “compulsory license” under which
certain limited uses of copyrighted works are permitted upon payment of
specified royalties and compliance with statutory conditions. For further information
about the limitations of any of these rights, consult the copyright law or
write to the Copyright Office.

The way in which copyright protection is secured is frequently
misunderstood. No publication or registration or other action
in the Copyright Office is required to secure copyright.
