In scholarly writing, you will often use someone else's work to add context to or support for your arguments. Often, these will be quotations from other authors, but you might also use art, photographs, images, music, or video. Under the principles of copyright law, these works are likely to be protected by copyright law, and the right to copy and distribute the work belongs exclusively to the copyright holder. Fortunately, there are exceptions to the copyright law which, under specified circumstances, allow the use of copyrighted works without explicit permission from the copyright holder. If none of those exceptions apply, however, you will need to request permission from the copyright holder before using his or her work.
