Explain two switch features of copyright law that affect researching information?
Well I'm not exactly sure what you are asking. There's a fair use exception for using parts of copyrighted information for teaching.
Or do you tight looking a copyright up? If there is no registered copyright, people would enjoy trouble knowing if what they do infringes on someone else's work. And that's why copyrights should always be registered. If it is, then the plaintiff would own a prima facie case to sue if someone infringes on their copyright. If it is not registered, it would be harder to sue, unless it is popular enough for empire to know the work was already created by someone else. This usually only requires that it be published in some form in the public domain. Source(s): http://en.wikipedia.org/wiki/Fair_use
