Referencing is a crucial aspect of academic writing. It ensures that the original authors of the sources you use in your work are properly credited and helps readers verify the information. With numerous referencing styles available, it’s important to understand the specifics of each to apply them correctly in your papers. This guide covers the most common referencing styles students should know, including APA, MLA, Chicago, and more.
Understanding Referencing
Referencing involves acknowledging the sources of information and ideas that you incorporate into your academic work. Proper referencing is essential to avoid plagiarism, provide evidence for your arguments, and give credit to the original authors.
Importance of Referencing in Academic Writing
Referencing plays a vital role in academic writing for several reasons:
Credibility: Citing sources enhances the credibility of your work.
Verification: Readers can verify the information and further explore the topic.
Acknowledgement: It acknowledges the contributions of other researchers and avoids plagiarism.
Overview of Common Referencing Styles

Differences Between Referencing Styles
Different referencing styles vary in their use of in-text citations, reference list formats, and specific guidelines. Understanding these differences is essential for correctly applying the appropriate style.
Choosing the Right Referencing Style for Your Paper
Selecting the right referencing style depends on your field of study, the requirements of your instructor, and the conventions of the academic discipline.
Common Mistakes in Referencing and How to Avoid Them
Common mistakes in referencing include incorrect citation formats, missing citations, and inconsistent use of styles. To avoid these errors, carefully follow the guidelines of the chosen style and double-check your references.
Tools and Resources for Managing References
Several tools and resources can help manage references, including:
How do I choose the right referencing style for my paper?
Choosing the right referencing style depends on your field of study and the requirements of your instructor. Common styles include APA, MLA, and Chicago.
What is the difference between in-text citations and a reference list?
In-text citations are brief references within the text, while the reference list provides detailed information about all the sources cited in the paper.
Can I use multiple referencing styles in one paper?
It’s generally not recommended to mix referencing styles in one paper. Consistency is key to maintaining clarity and credibility.
What should I do if I can’t find the publication date for a source?
If the publication date is unavailable, use “n.d.” (no date) in place of the year.
How do I cite a source with multiple authors?
The format for citing multiple authors varies by style. In APA, list all authors the first time, and for subsequent citations, use “et al.” after the first author’s name if there are more than two authors.
Can I use online citation generators for referencing?
Yes, online citation generators can be helpful, but always double-check their accuracy and ensure they follow the specific guidelines of your chosen style.
Conclusion
Understanding and correctly applying referencing styles is essential for academic writing. By familiarizing yourself with the guidelines of various styles, such as APA, MLA, Chicago, and others, you can ensure your work is credible, properly cited, and free from plagiarism.

The APA 6 guide was developed in line with the American Psychological Association in 2013. Publication manual of the American Psychological Association (6th ed.). Washington, DC: Author.
General Principles of APA 6 Formatting
Double-spacing throughout the paper.
Margins – 1″ (2.54 cm), while paper size should be 8.5″ x 11″
Times New Roman or Arial 12 pt. font (unless the instructions require a different font)
APA 6 papers contain running head(s) at the top of every page and page number. Page numbers are inserted flush right, while the paper’s title, written in UPPER CASE, is inserted flush left. Your title in the header should contain no more than 50 characters (including spaces and punctuation).
Papers written in APA 6 are divided into four sections:
Title Page
Abstract
Body
Reference List
Title Page
Running head: THE TITLE (with words’ Running head’ only on the title page)
All the following pages have a different header from the first page: THE TITLE
Title:
Your title should be inserted in the upper half of the first page.
You should not use more than 12 words for your title.
Use upper and lower case (avoid abbreviations and redundant words).
The title page should be double-spaced.
Insert the author’s name below the title.
Insert the educational institution below the author’s name.
Abstract
The abstract is written on a new page; this page should contain a page header (see above).
The word “Abstract” is centered on the new page. Do not use quotation marks, bold, italics, or any other formatting.
The text on the abstract page is NOT indented.
The abstract should contain only the most relevant information, such as research topic/thesis statement, research question(s), sample size/participants, research design/method, data analysis, results, and conclusions.
The abstract consists of a single paragraph (about 130-150 words) of double-spaced text.
If keywords are required, they are indented and written beneath the abstract paragraph. Do not forget to use italics for the word “Keywords.”
Headings
Level 1 heading should be Bold, Uppercase, and Lowercase
Level 2 should be Left-aligned, Bold, Uppercase, and Lowercase
Level 3 should be indented, with a bold lowercase heading with a period. Begin your text after the period.
Level 4 should be indented, bold, italicized, and lowercase heading with a period. Begin your text after the period.
Level 5 indented, italicized, lowercase heading with a period. When writing, begin your text after the period.
Reference List
The reference list is inserted at the end of your paper; any source you use must be included in the reference page and cited in the text.
Indent all lines after the first line in the entry (hanging indent); the lines should be indented one-half inch (1.27 cm) from the left margin of your paper.
Do not forget to invert authors’ names, such as last name and initials. Example: Cage, D. C.
If you have to cite more than seven authors, only the first six authors are listed, then an ellipsis is placed, and the last author’s name is listed after the ellipsis.
The reference list is always alphabetized by the first word in the reference entry (from A to Z).
When alphabetizing titles or group names as authors, go by the first significant word (disregard a, an, the, etc.)
If your reference has a group author, the name of the group can sometimes be abbreviated in the text—for example, the American Psychological Association can be abbreviated to APA. As with other abbreviations, spell out the name of the group upon first mention in the text and then provide the abbreviation.
If the name of the group first appears in parentheses in an in-text citation, put the abbreviation in brackets after it, followed by a comma and the year for the citation:
Example: The American Psychological Association (APA, 2011) suggested that parents talk to their children about family finances in age-appropriate ways.
Children should learn about family finances in age-appropriate ways (American Psychological Association [APA], 2011).
In the reference list entry, do not include the abbreviation for the group author. Instead, spell out the full name of the group.
Journal titles are always presented in full and capitalized:
Example: Archives of General Psychiatry
Do not alter the journal’s name:
Example: JAMA Psychiatry (NOT Jama Psychiatry)

APA 6 In-text citations
When citing references in a text using the APA format, focus on the author-date approach. This means that the author’s surname (without suffixes such as Dr. or Jr.) appears in the text, followed by the year of publication.
Direct quotations require the inclusion of the page number in addition to the authors’ names and years.
Example: (Leary, 2009, p. 137).
An author named in a signal phrase
APA format requires the use of the word and instead of the ampersand before the last author’s name when citing a work by multiple authors in the text.
Example: Greene and Kernis (2012) argued that every individual involved in the process of creation of software is responsible for its quality.
The author is not named in a signal phrase.
Example: The framework based on categorizing racial attributes does not consider numerous individual differences between ethnic groups (Holland, 2010).
A work by two authors
Example: The use of sterilization accounts for 3.2 percent of birth control methods in Christian communities (Purnell & Paulanka, 2016).
A work by three to five authors
List all authors the first time a work is cited in the text. However, in subsequent citations, only the first author’s name, followed by et al., along with the year of publication, should be placed.
Example: The limitations of the classification system preclude its use for the determination of specific health needs of ethnic minorities (Flatman, Flemming, & Drewett, 2009).
Example: Belonging to a racial group requires a differentiation between racial needs and those of the society at large (Flatman et al., 2009).
Six or more authors
Include only the name of the first author, followed by et al., along with the year of publication.
Example: Baxter et al. (2014) argued that statewide statistics do not reflect the real experiences of Muslims in the U.S.
Unknown author
When the source does not identify an author, cite it by the first few words of its title. The titles of books and periodicals have to be italicized, whereas titles of book chapters and articles must be placed inside quotation marks.
Example: Naturalism and the improvement of healthcare outcomes are the main principles of the provision of biomedicine in the U.S. (Biomedicine and Health Care, 2015).
Example: The healthcare services in Australia are based on the long-standing culture of nursing as well as national models of health and illness (“Health care approaches,” 2011).
Corporate Author
If the name of the group first appears in parentheses (as in the second example below), put the abbreviation in brackets after it, followed by a comma and the year for the citation:
Example: The American Psychological Association (APA, 2011) suggested that parents talk to their children about family finances in age-appropriate ways.
Example: Children should learn about family finances in age-appropriate ways (American Psychological Association [APA], 2011).
In the reference list entry, do not include the group author’s abbreviation. Instead, spell out the group’s full name.
Authors with the same last name
Include first initials followed by the last names in order to distinguish between authors with the same last name.
For example, The religious and spiritual beliefs of Arab American Muslims significantly influence their healthcare practices and health-seeking behaviors (M. Berndt, 2016; L. Berndt, 2016).
More than one work by the same author in the same year
Distinguish between works by the same author in the same year by including lowercase letters next to the year of publication in both in-text citations and reference list entries.
Example: Terminally ill patients find a source of strength in performing daily prayers and adhering to other religious duties described in their sacred texts such as the Bible and Quran (Robbins, 2011a).
Indirect sources
Provide the author of the source in a signal phrase and include a citation of the secondary source in parentheses. Note that only the secondary source has to be included in the reference list.
Example: Smith argues that “personalistic systems provide the most accurate representation of a patient’s identity” (as cited in Wescot, 2014, p. 213).
Citing sources without page numbers
When an electronic document has numbered paragraphs, use the abbreviation “para.” followed by the paragraph number (Hall, 2001, para. 5). If the paragraphs are not numbered and the document includes
headings, provide the appropriate heading, and specify the paragraph under that heading.
Example: Pinker and Smith (2013) went so far as to argue “that Chinese cultures condone the use of invasive health care procedures” (para. 11).
Example: According to Smith (1997) (Mind Over Matter section, 2018, para. 6)
FAQs
What’s the difference between APA 6th and 7th editions?
The 7th edition, released in 2019, introduced several changes, including simplified author guidelines (listing up to 20 authors in the reference list), updated guidelines for digital sources, increased flexibility in font choices, and a new format for student papers. However, many institutions still use the 6th edition, so always check which version is required.
How do I cite a source with no author?
When a source has no author, use the title of the work in place of the author’s name: In-text citation: (“Article Title”, 2020) Reference list: Article title. (Year). Publication Name. URL
Can I use first-person pronouns in APA style?
APA 6th Edition allows the use of first-person pronouns (I, we) in appropriate contexts, such as describing your research process or stating your position. However, use them sparingly and maintain a professional tone.
How do I cite multiple works by the same author in the same year?
