According to the U.S. Copyright Office, "Copyright is a type of intellectual property that protects original works of authorship as soon as an author fixes the work in a tangible form of expression. In copyright law, there are a lot of different types of works, including paintings, photographs, illustrations, musical compositions, sound recordings, computer programs, books, poems, blog posts, movies, architectural works, plays, and so much more!" You can read more about it on this page.
Copyright is a bit beyond our usual area of assistance as a Patent and Trademark Resource Center, but the PTRC Representatives will try to point you to resources if you have additional questions. You can contact us by email at lib-ptrc@osu.edu.
