How do I do in text citations in MLA format with no page number?
When a source has no page numbers, in-text citations for it can just include the author's name. The author-only in-text citation can be placed in parentheses or be part of the sentence in which the source is quoted or paraphrased. Here are some examples from the 7th Edition MLA Style Guide:
Example 1: Kurosawa's Rashomon was one of the first Japanese films to attract a Western audience.
Example 2: The utilitarianism of the Victorians "attempted to reduce decision-making about human actions to a 'felicific calculus'" (Everett).
You can read more about these rules in COM Library's Cite MLA Style LibGuide. Select the In-Text Citations tab and scoll down to the box titled "Page Number Unknown, With or Without Known Author".
