Which right does a copyright give to an author concerning their work?

A copyright grants an author the ability to prevent unauthorized duplication of their work, which is a fundamental aspect of copyright law. This right allows authors to control who can reproduce their work, ensuring that they retain ownership and authority over how it is used. By restricting duplication without permission, copyright protects the author's interests and the economic value of their creative content.

While authors may also have the right to create derivative works or sell their work, the primary focus of copyright is to prevent others from copying the original material without consent. This empowers authors to protect their intellectual property and incentivizes creativity and innovation within the arts and sciences.
