MLA or Modern Language Association and APA or American Psychological Association Citations are two citation systems commonly used to provide the necessary information and to acknowledge the sources of all the information supplied in a research paper. One of the common differences between the two is that MLA is used mostly by students in high schools, colleges, and universities when writing a research work that has to do with humanities and academic literary works whereas APA is used mostly when writing a research work that has to do with sciences, business, and sociology.
In MLA, the bibliography which contains all the information to be submitted about all the necessary citations to be done is known as "works cited page" in MLA. In contrast, it is known as "the reference" in APA.
If you are using APA, you will need to put only the last names of all the authors and editors, including their initials. In contrast, the full names of the first three authors or editors should be written if you are using MLA while you use “et al." for the rest.
