Copyright is a law that gives the person who created something, like a book, a song, a picture, or a movie, the right to decide how others can use it. Think of it as a special permission slip for your creative work. Copyright laws help creators earn money from their ideas and hard work. Because of copyright, no one can copy or use a creative work without the owner's permission.

If someone copies or changes a copyrighted work without permission, the owner can take legal action. This usually involves civil law, where the owner might ask for money for the damage caused. In very serious cases, copying a copyrighted work without permission could lead to fines or even prison.

Congress created copyright law to promote the progress of creativity, encouraging people to create works that can be enjoyed and, in a number of situations, used by everyone. Copyright law gives copyright owners rights that let them benefit from their creative works and this helps them keep creating.

 If something is protected by copyright, you might still be able to use it. First, you could ask the person who owns the copyright whether they will let you use the work. Second, there are some ways you can use works protected by copyright even without permission. But you can only do this if the law lets you, like if you make what is called a “fair use” of the work. If you want to use a copyright-protected work in one of these ways, check with your teacher, parents, or an adult that can help you figure out what types of things you can do. 

Copyright protection has a time limit, called the copyright term. For most people, copyright lasts for the life of the person who creates a work plus 70 years. After the end of the copyright term, a work goes into the public domain. Anyone can freely use works in the public domain. In fact, many authors use public domain works to create totally new works. One example is Shakespeare’s Romeo and Juliet. This famous play has been in the public domain for centuries, and many people have used it to make new movies and plays.
