The poster probably meant "fair use", which is an American term of copyright law. The UK, Canada, and other commonwealth countries have a concept known as "fair dealing" which is similar to, but different than fair use[1]. EU copyright law has explicitly permitted uses[2] which are exceptions to copyright restrictions. Research is one of them, but requires explicit attribution.
