Copyright Terms and the Public Domain
There may be items published on this site which I believe to be in the public domain: no longer protected by copyright laws and freely usable by anyone without permission. These items will be marked as such. To determine if an item is in the public domain, I am using the copyright terms described below. Although this site is published in Canada, there is some question of which country's copyright law is in effect, since Web publishing is essentially global. In the absence of any overriding constraints, copyright will be assumed to have expired 50 years after the death of the author.
Canada: The term of copyright is for the life of the author and for an additional 50 years from the end of the year in which he/she died. Therefore, as of 2003, any work by an author who died in 1952 or earlier is in the public domain. Since it is the year of the author's death that determines copyright expiration, this information will be provided if possible. Canadian copyright law is used as the basis for this site.
United Kingdom: The term of copyright is for the life of the author and for an additional 70 years from the end of the year in which he/she died. Therefore, as of 2003, any work by an author who died in 1932 or earlier is in the public domain. However, it is possible that works produced before the 1988 copyright act took effect are governed by the 1911 or 1956 copyright act, which provide a protection period of 50 years after the death of the author; if so (and this is not at all clear!), any work by an author who died in 1952 or earlier is in the public domain.
United States of America: Because of numerous changes to US copyright law, there are several terms of copyright. If a work was published before 1923, it is now in the public domain. If a work was published from 1923 to 1963 and it included an explicit copyright notice, it was protected for 28 years and could have been renewed for an additional 67 years. If not so renewed, or if it originally had no copyright notice, it is now in public domain. If published from 1964 to 1977 with a copyright notice, it is protected for 28 years for first term, with an automatic extension of 67 years for second term; if it had no copyright notice, it is in the public domain. Anything published from 1978 on is protected for the life of the author plus at least 70 years, and possibly up to 95 years.
Berne Convention/Universal Copyright Convention: Authors who live or publish in countries that are signatories of the Berne Convention for the Protection of Literary and Artistic Works, or to the Universal Copyright Convention (UCC), automatically receive copyright protection in all other countries that are also signitories. Most countries belong to at least one of these conventions. The international copyright conventions generally give authors of member countries the same level of copyright protection they give their own nationals. The Berne treaty establishes that copyright extends to 50 years after the author's death, and such copyrights are to be acknowledged by all countries that are signatories of the treaty.
