Whether you are a high school/university student or a scholar working on the first journal article, you must have encountered formatting/citation issues at least once. Depending on your subject area, you might have been required to format your paper either according to The Chicago Manual of Style, MLA, or APA style. There are many more, including CP and SAA, but the APA, MLA, and Chicago are the most common ones in academic writing. Used as an abbreviation for the American Psychological Association, APA format is normally used for papers concerning social sciences topics, such as psychology, economics, statistics, and education. Here I compiled the list of the most common issues that arise when formatting and/or citing a paper in the APA style.
