MLA format is commonly used in Literature and throughout the Humanities. It uses in-text notation similar to APA.
Consult the MLA Handbook for the full and official rules, but also check out the MLA section of Purdue University's online writing lab (see below) for online help. Their resources include a sample term paper that reflects the 2016 updates in MLA style.
See a librarian if you need help using this or any citation style.
