Include a URL or web address to help readers locate your sources. Because web addresses are not static (i.e., they change often) and because documents sometimes appear in multiple places on the web (e.g., on multiple databases), MLA encourages the use of citing containers such as Youtube, JSTOR, Spotify, or Netflix in order to easily access and verify sources. However, MLA only requires the www. address, so eliminate all https:// when citing URLs.
A “permalink” is a shortened, stable version of a URL. Look for a “share” or “cite this” button to see if a source includes a permalink. If you can find a permalink, use that instead of a URL.
