Determining whether your use of another's work can be considered fair use can be complicated, and there are pretty much no clear answers.
Fair Use around the world: Canada and countries that follow United Kingdom laws include a similar provision called Fair Dealing. Most other countries do not have a similar provision within their copyright (or intellectual property) laws.
As students, researchers, teachers, creators, consumers, and sharers of media, texts, and more, we all build on the ideas of others. Did you know that when you cite a quotation, create a parody, or modify and share a meme, that you’re benefiting from Fair Use, a four-factor exemption of U.S. Copyright Law (17 U.S. Code § 107)?
