The academic environment holds a strict, stringent, and focused approach to representing work in terms of writing, such as essays, research papers, science publications, etc.
Certain rules & regulations are laid along with specific citation styles that give a unified and structured system to represent the research work.
Among many, APA and MLA are common and primarily used; both are pretty similar, so there is little confusion.
Choosing APA or MLA purely depends on the work or questions one will answer or represent through their research.

Every academic journal, article, book, or research paper, is written brilliantly in a specific format and style to give a unique value to the reader.
Typically, the subject area of the research decides what format will be used to write the paper.
Understanding the difference between APA and MLA styles helps the author organise their write-up correctly and won’t distract the reader.
- In APA style, four sections are there, i.e. page title, an abstract of the research, body paragraphs with headings/sub-headings, and a list of references. In MLA style, only two sections are there, i.e. body in paragraph format and work cited pages. In MLA, the page title and an abstract are not included.
- In APA style, an in-text citation is in author-date format, whereas in MLA style, in-text citations are author-page format.
- In APA, the author’s last name is mentioned with the publishing date/year in parenthesis, whereas in MLA, the author’s name with the page number is cited.
- Pages referred to in APA are mentioned at the end in a single page as “References”, whereas, in MLA, it is mentioned as “Work-Cited”.
- APA format is used for social science like Sociology, Psychology, Nursing, Social Work, Criminology, Business, Education, etc. MLA format is used for humanities like Literature, History, Language, Arts, Philosophy, Theatre, Religion, Law, Anthropology, Politics, etc.

the way we quote sources on the web is quite different from the standardized ways of quoting sources. ALA and MLA look great to me but I never rememberd the difference and used to get confused with them. you are doing great job by giving us answers to differences.
the formatting is quite different in both ALA and MLA. But if you have used both types of formatting to quote sources then just by looking at them, you can tell whether it is ALA or MLA
