How long does copyright last?
In a literary or artistic work, other than a photograph
copyright endures for the lifetime of the author and 50 years after
the author's death or 50 years after the posthumous first publication
of his/her work. In a film, photograph or a computer program copyright
endures fifty years from the end of the year in which the work is made
available to the public or after the work is first published, whichever
is the longer period.The publishers also has copyright in respect of
the published edition (i.e. the edited typeface used) even if the original
material is no longer subject to copyright e.g. A new edition of a Shakespeare
play.
