About Public Domain

Public Domain


Public Domain is a status given to publications, creative works, or other types of works that are no longer protected by copyright.  No one legally owns these works, so they can be reused or repurposed by anyone!

Why do works enter the public domain? 

  • Copyright expiration:  the protections are no longer and place which depends on the type of work and when it was published. 
  • A copyright was not renewed by the copyright holder.
  • Dedication:  when a creator surrenders their copyright and gives it to the public for their use.  No Rights Reserved (also known as CC0) is a license that an author may use to show they did this, or it may appear on works known to be in the public domain.

How can public domain works be used? 

  • Publications and Presentations: public domain images can be included to provide examples or illustrations of concepts.
  • Teaching:  public domain works can be used as readings, assignments, translations, or labs.
  • Scholarly Activities:  reuse, repurpose, or integrate into current research.
  • Creative Tasks:  update, revise, or make a work inspired by something in the public domain.

If I reuse a public domain work, do I need to cite it?  Although these works are free of copyright restrictions, attributing a public domain work is good practice from the standpoints of academic integrity and the respect of intellectual property.  Using a public domain work does not violate copyright, but failing to attribute it or wrongfully claiming authorship is considered plagiarism as opposed to copyright infringement (Crews, 2020, pg. 58).  Therefore, citing a public domain work is just the ethically right thing to do!
