The Modern Language Association (MLA) style provides guidelines for formatting papers and citing sources to ensure consistency and avoid plagiarism. Key guidelines include double spacing the text, writing out the title in full in the header, indenting the first line of each paragraph, and citing sources with parenthetical references linked to an alphabetized Works Cited page listing full source information. MLA style dictates specific formatting for elements like block quotations, omitting or adding words in quotations, and outlining.
