document in public domain, after 1923

Jump to: navigation, search

Anonymous[1] documents published in the United Kingdom between January 1st, 1923 and January 1st, 1942 are in the public domain in the following countries (as of 2012):

  • United Kingdom itself: the copyright on an anonymous work expires 70 years after its publication;[2]
  • other countries of the European Union: the "shorter term" rule applies to foreign works, and foreign documents which are already in the public domain in their home country are not protected in the European Union.[3]

They are not in the public domain in the United States, where foreign works which were not already in the public domain in their home country as of January 1st, 1996 were subject to copyright restoration, and are protected until 95 years after their date of first publication.[4] The publication of advertising material published in the United Kingdom in that period probably falls under fair use for US legislation, and it is thus accepted in Camera-wiki.
