In MLA format, when you directly quote, paraphrase, or summarize an outside source, you must always use in-text citations.
In MLA formatting, an in-text citation is used to tell readers that information comes from a different source.
If there is more than one source of information, then you must provide a citation at the end of the document.
In paraphrasing, you express the idea of another author or scholar in your own words.
While giving in-text citations in MLA format, one must provide the author's last name and page number in the text while a detailed citation should be given at the end.
