MLA 8th edition is intended to be a universal set of guidelines to apply to any type of source. Each source in the Works Cited is based on a list of core elements (see image). Not all sources will have all nine elements.
For in-text citing, MLA follows the author-page format. For internet sources, you do not need to include the paragraph number unless part of the source. When there is not an author, use a shortened title of the work. Use quotation marks for a short work (e.g. article, blog post) or italics for a longer work (e.g. plays, books, television shows, entire websites).
