About Public Domain
Public Domain is a status given to publications, creative works, or other types of works that are no longer protected by copyright (see left image). No one legally owns these works, so they can be reused or repurposed by anyone!
Why do works enter the public domain? Copyright works can enter the public domain for a variety of reasons. Copyright protection eventually expires, and when this happens depends on the type of work and when it was published. Sometimes a copyright holder did not renew their copyright, so the work entered the public domain. Another reason is known as dedication, or when a creator surrenders their copyright and gives it to the public for their use. No Rights Reserved (also known as CC0, see left, lower image) 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?
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 (Crews, 2020, pg. 58). Therefore, citing a public domain work is just the ethically right thing to do!
