Copyright protection usually lasts for seventy years after the death of the last publicly identified author. Anonymous or pseudonymous works gain protection for the later of 70 years after the work is lawfully made available to the public or 70 years from creation. If national legislation makes particular provision for collective works or for a legal person (i.e. a body corporate) to be a rights holder the term of protection of calculated in the same way as for anonymous or pseudonymous works, with the exception that if any natural persons who created the work are given credit in versions made available to the public, the term of protection is calculated according to the lives of those authors. Art. 1, Directive 93/98/EEC).
