The Difference between Copyright Infringement and Plagiarism—and Why It Matters; Library Journal, 8/17/16

Rick Anderson, Library Journal; The Difference between Copyright Infringement and Plagiarism—and Why It Matters:

"TELLING THE DIFFERENCE

If you were to take Alice’s Adventures in Wonderland, change the title and the characters’ names, and pass it off as your original work, that would be plagiarism. However, there would be no copyright infringement, because Alice’s Adventures in Wonderland is in the public domain and therefore no longer subject to copyright.

On the other hand, if you were to take 50 Shades of Grey—a work currently in copyright—change the title and the characters’ names, and pass it off as your original work, that would constitute both plagiarism and copyright infringement. Stealing the author’s work in this way and selling an unauthorized derivative of it would not only be unethical; it would also be illegal.

Under U.S. law, it might be an example of stealing that rises to the level of a felony punishable by imprisonment, depending on its demonstrable financial impact on the legitimate rights holder."
