Limitations and exceptions to copyright
Limitations and exceptions to copyright are provisions, in local copyright law or the Berne Convention, which allow for copyrighted works to be used without a license from the copyright owner. Limitations and exceptions to copyright relate to a number of important considerations such as market failure, freedom of speech, education and equality of access (such as by the visually impaired).
