Public domain content refers to creative works that are not protected by copyright, meaning anyone can use, share, or modify them without seeking permission. This includes literature, music, art, and other forms of media that have either expired copyrights or were never eligible for copyright protection. Examples of public domain works include classic novels like Pride and Prejudice and famous paintings like The Starry Night. The public domain is important because it allows for the free exchange of ideas and creativity. When works enter the public domain, they can be used by educators, artists, and the general public to inspire new creations or to provide access to cultural heritage. This fosters innovation and ensures that knowledge remains accessible to everyone.
