Q. How long does copyright last?
Copyright usually provides protection for a specific period of time. When that time elapses, the material is considered to be in the public domain. Copyright normally exists until 70 years have elapsed from the year of the creator's death, but even if the literary content of a work is out of copyright, copyright exists in the typographical arrangement of a published work for 25 years after the end of the year in which the edition was first published.
