What kinds of things are copyrighted? Copyright protects any “original works of authorship” that are somehow "fixed" in time and space - e.g., written down, posted on the web, scribbled on a cocktail napkin. All of these are copyrighted:
Who owns copyright?
What cannot be copyrighted?
How long does copyright last? A long time – generally speaking, copyright lasts 70 years after the life of the author. If a work is created by a corporation or employer, copyright lasts 95 years past the publication date. See this site for more information.
What kinds of things are no longer covered by copyright? Works published a long time ago – before 1923 – are no longer covered by copyright. These are thus said to be in the “public domain.” There are other ways to release a copyright, intentionally to share works with others, such as Creative Commons.
Copyright vs. Plagiarism: Copyright is different from plagiarism – “plagiarism” is an appropriation of someone else’s work without giving proper credit. You can plagiarize without infringing a copyright.
