How do you do an MLA in-text citation for an online source?

There are numerous resources available online that you can utilize in order to help you learn how to create in-text citations in both MLA and APA format.

When it comes to creating in-text citations in MLA format, you're going to want to open with quotation marks, add the text you've chosen (verbatim) while omitting ending punctuation, close with quotation marks, cite the author's last name and the page number (if applicable) inside parentheses, and then place the period at the end.
