Archimedes' screw. Public domain, from Chambers's Encyclopedia (Philadelphia: J. B. Lippincott Company, 1875). Added to illustrate article en:Archimedes.
This media file is in the public domain in the United States. This applies to U.S. works where the copyright has expired, often because its first publication occurred prior to January 1, 1929, and if not then due to lack of notice or renewal. See this page for further explanation.
This image might not be in the public domain outside of the United States; this especially applies in the countries and areas that do not apply the rule of the shorter term for US works, such as Canada, Mainland China (not Hong Kong or Macao), Germany, Mexico, and Switzerland. The creator and year of publication are essential information and must be provided. See Wikipedia:Public domain and Wikipedia:Copyrights for more details.

Dette verket er falt i det fri i Noreg, og dei landa som har opphavsrettsleg vernetid på 70 år etter opphavsmannen sin død, eller kortare.
For å kunne lagres på Commons må verket både være offentlig eiendom i USA og i opphavslandet. Vernetiden kan i noen tilfeller være lengre enn 80 år i USA, så i tillegg til dette merket trengs det et eget merke som forklarer hvorfor verket er offentlig eiendom (public domain) i USA.
Note that a few countries have copyright terms longer than 70 years: Mexico has 100 years, Jamaica has 95 years, Colombia has 80 years, and Guatemala and Samoa have 75 years. This image may not be in the public domain in these countries, which moreover do not implement the rule of the shorter term. Honduras has a general copyright term of 75 years, but it does implement the rule of the shorter term. Copyright may extend on works created by French who died for France in World War II (more information), Russians who served in the Eastern Front of World War II (known as the Great Patriotic War in Russia) and posthumously rehabilitated victims of Soviet repressions (more information).
