Pre-1923 Publication Not in Copyright Public Domain
. . . the U.S. copyright in any work published or copyrighted prior to January 1, 1923, has expired by operation of law, and the work has permanently fallen into the public domain in the United States. For example, on January 1, 1997, copyrights in works first published or copyrighted before January 1, 1922, have expired; on January 1, 1998, copyrights in works first published or copyrighted before January 1, 1923, have expired. Unless the copyright law is changed again, no works under protection on January 1, 1999, will fall into the public domain in the United States until January 1, 2019.
