According to the U.S. Constitution, the purpose of copyright is "to promote the progress of science and the useful arts."
Most everything in print and on the internet is protected by copyright. This means that the creator of an original work has exclusive rights to how it is used and distributed.
Copyright protects original works fixed in a tangible medium. Examples include movies, poetry, prose, software, artwork, musical notation, recorded music, animations, video, a web page, blog posts and comments, architectural drawings, or photographs.
Check the works you are using for statements about copyright, ownership, and intellectual property rights. It is your responsibility to respect these rights since you can be liable for any infringements.
Works in the public domain, such as a work first published in the United States before 1924, are no longer protected by copyright. Use the digital copyright slider to determine whether a work published in the United States is in the public domain or covered by copyright.
You can sometimes use copyrighted items for teaching and research purposes under fair use provisions or specific educational exceptions. Works with an open license such as a Creative Commons license can also be legally shared with appropriate attribution or other specified conditions.
