Accurately citing your sources will resolve potential plagiarism issues (see Plagiarism tab), but it's also necessary to understand the basics of copyright law so that you don't infringe on someone else's intellectual property rights. In essence, copyright protects the creators of original works from unauthorized use of their work. Ideas and facts can't be copyrighted, but expressions of ideas, such as books, photographs and music are protected by copyright, even if not formally published and even if you don't see a copyright symbol © on the work. (See the list of what is copyright-protected below.)
Given the ownership protections of copyright law, how can you legally and ethically use the expressions of others in your own work without contacting the owner for permission? Fortunately, the U.S. Copyright Law specifies certain limitations on copyright, the four criteria of fair use, to facilitate and enhance the educational process. The fair use criteria can sometimes override the rights of a creator if you apply them in a thoughtful, reasonable manner and give proper attribution (cite the work). See the following section, What is Fair Use?, for further information.
As you can see, assessing fair use is never clear cut! If you're not sure whether you can use a resource for a project or presentation or how much you can use, ask your friendly librarian.
Works of original authorship that have been "fixed in tangible form" [17 USC Sec.102(a)] in the following categories:
Copyright does not protect:
Materials in the public domain that are therefore not copyright-protected; use this handy slider to determine if a work is still copyright protected.
In general, copyright exists from the moment the work is created, and copyright registration may not be needed.
More information about copyright registration can be found here: Copyright Registration FAQs.
It's always nice to find a bargain, and in some cases, there are works you can use for any purpose, including your own personal blog or website, for free! But remember, it's always best to give credit where credit is due: cite the source unless the source specifically states that you don't need to. Here are some examples of free resources:
