How Licenses Work
A licence is, at heart, about permission. In the context of copyright, a licence is about the permission granted by the copyright owner to another person to use a copyright-protected work, subject to negotiated terms and conditions, such as payment.
Often, licences are negotiated between a copyright owner and a user, outlining the specific ways in which someone can use a work for a limited period of time. In this way, licences frequently look like commercial agreements or contracts. However, because a licence is, at heart, about permission, a licence can be granted informally, including over email and in some cases, it may even be spoken and be no less valid and enforceable.
Each institution will have a different approach to licensing content so it’s important to check what licences are in place at your university or college. Ask the person or office designated to answer copyright questions or check your institution’s copyright guides. Your university or college library is a good place to start.
