As you finish your first drafts, you will be working on Works Cited pages and starting to perfect your in-text citations. Here is a link to the Purdue OWL MLA Style Guide:
https://owl.purdue.edu/owl/research_and_citation/mla_style/mla_formatting_and_style_guide/mla_general_format.html
There is an index on the left that will guide you to the answer to almost any question you have.
In addition, many of the texts you are using come from larger collections, or books. Here are links to the Amazon page for each full book, which will contain all the information you will need for your Works Cited page.
