This page helps users determine whether a given work is in the public domain in the USA where Wikisource server is hosted, and which template to use.

If a work is in the public domain in Canada but not in the USA, without license compatible with the Creative Commons Attribution/Share-Alike License 3.0 and the GFDL, please post it on Canadian Wikilivres (requiring username as IP users cannot edit there).

This document attempts to clarify whether copyright applies but see also Copyright policy and Copyright tags for categories to use.

Copyright terms by country[সম্পাদনা]

These tables outline the estimated length of time of copyright per country[৭][৮][৯]. 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:

Country Copyright length
Bangladesh life + 50
Bhutan life + 50
India life + 60 for literary or musical works or artistic works, publication + 60 for others[১০].
Pakistan life + 50
United Kingdom life + 70
United States of America expired for works published before 1923; 28 or 95 years for works copyrighted 1923-1963; 95 years for works copyrighted 1964-1977; thereafter life+70.
