The similarities between the citation forms begin with the in-text citation. Both require that you provide the source information within parenthesis (i.e., Bond) if it is not already provided within your text. Alternatively, both require some kind of guideline back to your works cited page even if you already quote the author in your text (i.e, in MLA you would quote the page number even if you had shared the name of the author in the text, while in APA, you would quote the year of the publication the author you already quoted had published his/her article or other document). Both include works cited pages and similar structure of always providing source information, no matter what the citation is.
The differences between the citation forms are mainly in what information each considers relevant. In MLA, page numbers (along with the author) are cited, while in APA, dates of publication (along with the author) are cited. Although APA does provide page numbers, it places more of a stress on years and dates than MLA. Another difference between the two consists within the works cited page, where information is rearranged slightly differently when providing the citation sources.
