"In-text citation" means that you refer to (or cite) the ideas or words of another as soon as you write about them in your paper. There are several ways to do this: using quotation marks for exact words, summarizing or condensing without changing the meaning, and paraphrasing or using your own words.
Here are specific examples of ways to handle in-text citation in APA and MLA format.
