Notes:

1922 FREEZE: The Sonny Bono Copyright Term Extension Act added twenty years to copyright terms. Public Law 105-298, 112 Stat. 2827 (1998). This explains why works published after 1922 are "frozen" until 2019. Works published in 1922 and earlier had already gone into the public domain at that time the law went into effect in 1998. This Act was upheld by the Supreme Court  in Eldred v Ashcroft, 537 U.S. 186 (2003) at http://www.supremecourtus.gov/opinions/02pdf/01-618.pdf . For more information see 长期免费更新ssr节点

FOREIGN WORKS: Although works that fall into the public domain have not had their copyrights restored by the Bono Act, it should be noted that some foreign works have had their copyrights restored under the Uruguay Round Agreements Act (URAA). Works from certain countries that did not comply with formalities of U.S. law were restored as of January 1, 1996. For more information, see United States. Copyright Office. Circular 38b, "Highlights of Copyright Amendments Contained in the Uruguay Round Agreements Act (URAA-GATT)," at http://www.copyright.gov/circs/circ38b.pdf Additionally, libraries in California, Oregon, Washington, Arizona, Montana, Idaho, Nevada, Alaska, Hawaii, Guam and the Northern Mariana Islands should note that a controversial 1996 ruling in the US Ninth Circuit may imply that certain foreign works published between July 1, 1909, and December 31, 1922, are still subject to copyright, if they had neither been published in the US, nor published with a copyright notice recognized by US law, prior to 1923. Twin Books v. Walt Disney Co., 83 F. 3d 1162 (9^th Cir. 1996).

UNPUBLISHED WORKS - NONE UNTIL 2003: An unpublished work that was not registered with the Copyright office had perpetual copyright under the common law. The Copyright Act of 1976 ended perpetual copyright and gives these works the same terms as published works since 1978. However, the Act also gave a grace period that ends December 31, 2002. This is why the chart says "NONE" before 2003. Additionally, if an unpublished work was published by December 31, 2002, the copyright does not expire before December 31, 2047. 17 U.S.C. Sec. 303 (2001).

WORKS PUBLISHED SINCE 1978: For works published 1978 and later, the term is for the life of the author plus 70 years for natural persons. Works by corporate authors and anonymous authors remains the same: 95 years from date of publication or 120 years from date of creation (whichever is less).

RENEWALS: Copyright renewals were necessary for works published or registered before January 1, 1964. Works at that time had a 28 year copyright term, which could be renewed. Less than 10% of all copyrights were renewed and fewer than 5% of copyrighted books and pamphlets were renewed during that period according to a 1961 Copyright Office study. James J. Guinan Jr. Duration of copyright. In Copyright law revision.

June 1999) at http://www.loc.gov/copyright/circs/circ22.html. Also see Circular 15. "Renewal of Copyright." (Rev. June 1999) at http://www.copyright.gov/circs/circ15.html. For works registered since 1978, an online search siteis available at the United States Copyright Office at http://www.loc.gov/copyright/rb.html/.

LIBRARY EXCEPTION: First, note that this exception does not apply to musical works, pictorial, graphic or sculptural works, nor to motion pictures or other audiovisual works other than audiovisual works dealing with news. The exception reads:

"(h) (1) For purposes of this section, during the last 20 years of any term of copyright of a published work, a library or archives, including a nonprofit educational institution that functions as such, may reproduce, distribute, display, or perform in facsimile or digital form a copy or phonorecord of such work, or portions thereof, for purposes of preservation, scholarship, or research, if such library or archives has first determined, on the basis of a reasonable investigation, that none of the conditions set forth in subparagraphs (A), (B), and (C) of paragraph (2) apply.

(A) the work is subject to normal commercial exploitation;

(B) a copy or phonorecord of the work can be obtained at a reasonable price; or

(C) the copyright owner or its agent provides notice pursuant to regulations promulgated by the Register of Copyrights that either of the conditions set forth in subparagraphs (A) and (B) applies.

(3)The exemption provided in this subsection does not apply to any subsequent uses by users other than such library or archives.

(i) The rights of reproduction and distribution under this section do not apply to a musical work, a pictorial, graphic or sculptural work, or a motion picture or other audiovisual work other than an audiovisual work dealing with news, except that no such limitation shall apply with respect to rights granted by subsections (b) and (c), or with respect to pictorial or graphic works published as illustrations, diagrams, or similar adjuncts to works of which copies are reproduced or distributed in accordance with subsections (d) and (e)." 17 USC Sec. 108

WORKS MADE FOR HIRE: Works Made for Hire are works (1) prepared by an employee within the scope of his or her employment; or (2) specially ordered or commissioned for use as a contribution to a collective work, as a part of a motion picture or other audiovisual work, as a translation, as a supplementary work, as a compilation, as an instructional text, as a test, as answer material for a test, or as an atlas, if the parties expressly agree in a written instrument signed by them that the work shall be considered a work made for hire. For more detail, see United States. Copyright Office. Circular 9, "Works Made for Hire under the 1976 Copyright Act," at http://www.copyright.gov/circs/circ9.html.

ssrr手机版添加订阅地址Presumption as to Author's Death. After a period of 95 years from the year of first publication of a work, or a period of 120 years from the year of its creation, whichever expires first, any person who obtains from the Copyright Office a certified report is entitled to the benefit of a presumption that the author has been dead for at least 70 years. Reliance in good faith upon this presumption shall be a complete defense to any action for infringement under this title. 17 USC Sec. 302(e) (2001).

TERMS END DECEMBER 31 EACH YEAR: Copyright terms expire at the end of the calendar year in which they are due to expire. Thus a copyright actually can last, for example, 95 years and 5 months. 17 U.S.C. Sec. 305 (2001).

FOR WORKS STILL UNDER COPYRIGHT- GET PERMISSION. If you can track down the copyright owner (see United States. Copyright Office. Circular 22."How to Investigate the Copyright Status of a Work" (Rev. June 1999) at http://www.loc.gov/copyright/circs/circ22.html), get permission. See Georgia Harper, University of Texas.
