Copyright terms by country

These tables outline the estimated length of time of copyright per country^[7][8][9]. Laws regarding anonymous works, corporate-authored works, or non-literary works vary per country. This is not intended to be used as a legal guideline since it cannot reflect the complexity of the copyright laws in effect at any one time and since copyright laws are changing continuously; this section simply provides a useful summary as part of a more in-depth research. See also the following Wikipedia copyright length lists for further information:
