Understanding copyright guidelines can be a daunting task. Sometimes it can be difficult to determine what is copyright protected and what is in the public domain.
- United States works published before 1923 are now in the public domain.
- Works published between 1923–1963 are protected for a total of 95 years, providing the work’s copyright was renewed in the 28th year. If it wasn’t then it is now in the public domain.
- Items published between 1964–1977 are copyright protected for 95 years.
- Finally, works created on or after January 1, 1978 are copyright protected for the life of the author plus 70 years thereafter. Works for hire have a term of 95 years from publication or 120 years from creation, whichever expires first.
An important exception to these terms is in the area of Sound Recordings. [See below for additional information]
Determining what can be legally used under Fair Use guidelines for educational or scholarly activities can also be confusing. The following is a good rule of thumb.
- Single chapter or 10 percent of published book
- Article from a journal or newspaper
- Short story, essay, or poem from a published work
- Chart, graph, diagram, or cartoon from a published work
- 10 percent of a musical composition, movie, photographs, or numerical databases from a published work
