The term of copyright can be confounding since there have been so many modifications to the term over the years. For this purpose, it is useful to consult a term chart. But while different works published or created at different dates may have different terms, the drop dead termination year for any work published or created by 1923, has now terminated as of New Year's Day 2019.
In 1998, the Sonny Bono Copyright Term Extension Act extended the copyright term of all works not then in the public domain by twenty years from 75 years to 95 years. Thus, works in the public domain by 1998 consisted of works first published in 1922 and earlier (1922 + 75 = 1997). But works first published in 1923 received an extra 20 years of life -- to 95 years -- since their term had not yet expired as of 1998. Thus, these works have now termed out as of the close of the last day of 2018 (1923 + 95 = 2018).
