Learning how to write an MLA reference page is very important because you will be doing it over and over again while writing academic papers.
You should title your page as a Works Cited page or a Literature Consulted, or a Works Consulted. It varies depending on what you would like to write. Then you should list your references or primary and secondary works such as books and journals that you have referenced in your paper. You should list them alphabetically and after you've listed the name of the author, last name followed by first name, you are going to list the book from which this author wrote. Then, publishing information. You are not only going to list the publisher, but also the city which it came from.
There are so many different ways to make a Works Cited page in MLA format. Your professor might tell you that you are going to be doing an MLA formatted page but they might give their own reference guide on how they would like you to format it. Make sure that you check with the professor and get their ideas on what they think the Works Cited page should look like. Make sure you are doing whatever your particular professor wants.
