The Modern Language Association (MLA) was founded in 1883. It has over 26,000 members representing 100 countries. They publish four journals and a number of books each year.
The MLA style of presentation in writing is the most used style to write papers within the liberal arts and humanities. So if you are student in the liberal arts or humanities or if your profession is one of these, you will most likely use the MLA style in your writing for citing works and for how your paper is formatted.
One of the best sources to understand the MLA style of writing is the Purdue OWL Online Writing Lab. It can be found at: https://owl.english.purdue.edu/owl/resource/747/01/
A good source for the Works Cited list is the Washington library guide. It can be found at: http://www.lib.washington.edu/help/guides/44mla.pdf There is also the Cornell University Library guide to citations in MLA. It can be found at: https://www.library.cornell.edu/research/citation/mla Just remember that the Works Cited list is always on a separate page at the end of your document.
