What is copyright?

Copyright is a form of legal protection automatically provided to creative works such as books, music, or art.

Copyright law is intended to encourage people to create new works. By limiting how others can use a newly-created work for some period of time, copyright law gives creators more control over the use of their works and increases their potential for compensation.

According to the law, only the person who controls the copyright (originally the creator) is allowed to:

  • reproduce the work
  • distribute copies of the work to the public
  • perform or display the work publicly
  • create derivative works; in other words, to create new works based closely on the original (such as a translation of a book from one language into another, or making a book into a movie)

The creator of a copyrighted work can give others permission to do these things with the work and can completely transfer these rights to someone else in a way that gives up these rights for themselves. For example, a book author will often transfer their copyrights to a publisher in exchange for money related to the sales of the book. After that transfer, authors can no longer give permission to anyone else to do these things and needs permission from the publisher to do these things themselves.

The creator, or person the creator transfers their rights to, is said to “control copyright” in the work and sometimes described as the copyright owner.

When someone other than the copyright owner uses the work in one of these protected ways without permission (or other justification under copyright law), it is called copyright infringement.
