Frequently Asked Questions
What is the difference between APA, MLA, and Chicago citation styles?
APA (American Psychological Association) is primarily used in social sciences, psychology, education, and business. It emphasizes the date of publication with author-date in-text citations like (Smith, 2023). MLA (Modern Language Association) is used in humanities, literature, and liberal arts, with author-page in-text citations like (Smith 45). Chicago Manual of Style offers two systems: notes-bibliography (using footnotes, common in history and arts) and author-date (similar to APA, used in sciences). Each style has distinct rules for formatting the reference list, handling multiple authors, and citing different source types. Your instructor or publisher will specify which style to use.
What are hanging indents and why do citation styles require them?
A hanging indent is a formatting style where the first line of a reference entry starts at the left margin and all subsequent lines are indented, typically by 0.5 inches (1.27 cm). All major citation styles (APA, MLA, Chicago, Harvard) require hanging indents in the reference list or bibliography. The purpose is to make the first element of each entry (usually the author's last name) visually prominent, making it easy to scan the alphabetical list and find specific references. In Microsoft Word, you can create a hanging indent by selecting the text, going to Paragraph settings, and setting Special to Hanging. In Google Docs, use the ruler or Format menu. Proper formatting of the reference list, including hanging indents, is part of the grading criteria in most academic assignments.
How often do citation style guides update and what changes?
Major citation style guides update every several years to reflect changes in publishing and technology. APA released its 7th edition in 2019 (previous was 6th in 2009), with major changes including new rules for DOI formatting, inclusive language guidelines, and simplified rules for multiple authors. MLA published its 9th edition in 2021 (8th was 2016), introducing optional elements and a more flexible containers system. Chicago released its 17th edition in 2017 (16th was 2010). Updates typically address how to cite new types of digital sources, simplify complex rules, and reflect changes in publishing practices. Students should always verify which edition their institution requires, as some professors still follow older editions while others adopt the latest version immediately.
