APA Referencing Guide

Introduction to APA Referencing

The American Psychological Association (APA) referencing style is a widely used citation format in the social sciences, education, and psychology. It provides a uniform way to cite sources in academic writing, ensuring that authors receive proper credit for their ideas and research, while allowing readers to locate the original sources.

Why Use APA Referencing?

Gives proper credit to original authors
Helps readers find and consult sources
Supports academic integrity and prevents plagiarism
Provides a standardized format for academic writing

In-Text Citations

In APA style, in-text citations include the author's last name and the year of publication. These citations allow readers to locate the complete source information in the reference list.

Basic Format

(Author, Year)

Examples

According to Smith (2020),...

Research shows that... (Johnson, 2019).

Recent studies (Brown & Lee, 2021) suggest...

Findings indicate... (Anderson et al., 2018).

Direct Quotes

When directly quoting a source, include the page number:

"Quote here" (Author, Year, p. XX).

Reference List

The reference list appears at the end of your document and provides complete bibliographic information for all sources cited in the paper. References should be listed alphabetically by the first author's last name.

Basic Reference Format

Author, A. A. (Year of publication). Title of work: Capital letter for subtitle. Publisher.

Source Type Examples

Books

Author, A. A. (Year of publication). Title of work: Capital letter for subtitle. Publisher.

Digital Object Identifier (DOI)

For most scholarly articles, include the DOI in the reference entry. The DOI is a permanent alphanumeric string that provides a persistent link to content on the internet.

Author, A. A., & Author, B. B. (Year of publication). Title of article. Title of Periodical, volume number(issue number), pages. https://doi.org/xxxx

Formatting the Reference List

Begin on a new page
Label the page "References" (centered, bold)
Double-space all entries
Use a hanging indent (first line flush left, subsequent lines indented)
Alphabetize by the first author's last name
Italicize titles of books, journals, and reports
Capitalize only the first word of article, book, or chapter titles, and proper nouns

Common Mistakes to Avoid

Incorrect formatting of author names (invert names, use ampersand before last author)
Improper capitalization in titles
Missing publication dates or dates in parentheses when they shouldn't be
Omitting DOI when available
Inconsistent or incorrect punctuation
Failing to alphabetize correctly
Not providing complete publication information
