As a general rule, copyright protection lasts for the life of the author plus 70 years.
There are several exceptions to the general rule to keep in mind.
- All works published in the United States before 1923 are in the public domain.
- Works published after 1922, but before 1978 are protected for 95 years.
- For anonymous work or a work for hire, the copyright lasts for 95 years from the year of its first publication. Or 120 years from the year of its creation. Whichever expires first.
