A guide to current copyright regulations, fair use, and the public domain.

Terms of Protection

Since the 1976 law and subsequent amendments in 1992 and 1998, the term of copyright protection has gotten longer and longer. The length varies by when the work was created and also depends on if/when the work was published, how many people were involved in its creation, and whether it was created in the U.S. or not. 

The graphic here shows the extension of copyright protection through the Congressional Acts. At this point, we are in the purple range*.

A single-author work fixed in a tangible form: 
  • life of creator + 70 years
Joint work, more than 1 author, not work-for-hire:
  • 70 years after the last surviving author’s death
Works made for hire (for an employer):
  • 95 years from publication or 120 years from creation, whichever is shorter
Anonymous and pseudonymous works (unless the author’s identity is revealed in Copyright Office records):
  • 95 years from publication or 120 years from creation, whichever is shorter

These rules refer to works created in the U.S. since 1978.

For more specific guidelines for works created before 1978 with or without the © symbol, see the Digital Copyright Slider.

What does 1978 have to do with anything?

Prior to the 1976 law (which took effect in 1978), works were copyrighted starting on the date they registered with the © icon for an initial period of 28 years, with the possibility of one 28-year renewal. The 1976 law extended the renewal period to 47 years, for a total term of 75 years of protection. The 1998 law (aka the Sonny Bono Act) extended the term another 20 years, for a total of 95 years (28+47+20).
