The document discusses different styles used for formatting academic writing and referencing sources. It describes several major referencing systems used in different academic disciplines, including MLA, APA, Harvard, IEEE, Vancouver, and Chicago/Turabian styles. For each style, it provides details on formatting in-text citations and reference list entries. It also introduces the Purdue OWL as an online resource for guidelines on these different styles.

1. Reference Systems
Styles of Formatting
ACADEMIC WRITING

2. Systems of Referencing
• several main systems of referencing in
the academic world;
• used by different subjects;
• the most important point is to be
consistent (i.e. to use the same font size,
punctuation, etc. throughout).

3. Main Referencing Systems
for essays and academic articles
MLA (Modern Language Association) - in various humanities
disciplines, e.g. language arts, cultural studies.
Harvard system - for the social sciences and business
APA (the American Psychological Association) Variation of the
Harvard style – for social sciences, e.g. business, economics,
psychology, sociology, nursing.
IEEE (The Institute of Electronic and Electrical Engineers style) – for
technical fields, particularly computer science.
Vancouver system – for medicine and science.
Chicago/Turabian style – for business, history, literature, and the
Fine Arts

4. The MLA style
In-text citation will be the author’s last name (or abbreviated title) with a page number,
enclosed in parentheses
If the essay provides a signal word or phrase -usually the author’s last name -the
citation does not need to also include that information

5. MLA. List of Works Cited
•The first author’s surname comes first in the
reference list.
•This is followed by his or her first name, but
first names then come first for any additional
authors. Dates of the publications are given after
journal titles, or at the end of the references for
books, etc.
•The list is ordered alphabetically.

6. MLA. List of Works Cited example
Begin the entry with the author’s last name, followed by a comma
and the rest of the name, as presented in the work. End this
element with a period.

7. The Harvard System
Smith (2009) argues that the popularity of the
Sports Utility Vehicle (SUV) is irrational, as
despite their high cost most are never driven
off-road. In his view, ‘they are bad for road
safety, the environment and road congestion’
(Smith, 2009: 37).

8. The APA style
Colloquially known as the ‘name(date)’ system:
• an author’s surname in the text is followed by the date of the publication in brackets;
Research suggests that the Purdue OWL is a good resource for students (Atkins, 2018).
Atkins (2018) suggests that the Purdue OWL is a good resource for students.
• entries in the reference list are listed alphabetically, starting with the name and
the initials of the author(s) followed by the date of publication for each entry.

Zammuner, V. L. (1995). Individual and co-operative computer writing and revising: Who
gets the best results? Learning and Instruction, 5(2), 101–24.

9. IEEE
In-text citations: the authors in the text are numbered in order of their appearance
in the text, sometimes without their names, and the numbers are enclosed in square
brackets.
The reference list is then numbered sequentially. Names are presented with the
initial(s) first, followed by surnames.
Dates of the publications are given after journal titles, or at the end of the references
for book, etc.
Journal titles are sometimes abbreviated.
For example:
[1] M. Sharples, Ed., Computer Supported Collaborative Writing. London: Springer-
Verlag, 1993.
[2] V. L. Zammuner, ‘Individual and co-operative computer writing and revising: Who
gets the best results?’ Learning and Instruction,vol. 5, no.2, pp. 101–24, 1995.
[3] C. Tang, ‘Effects of collaborative learning on the quality of assignments,’ in Teaching
and Learning in Higher Education, B. Dart and G. Boulton-Lewis, Eds. Melbourne:

[4] B. W. M. Speck, T. R. Johnson, C. P. Dice and L. B. Heaton, Collaborative
Writing: An Annotated Bibliography. Westport, Connecticut: Greenwood Press, 1999.

10. The Vancouver style
Named after its inception following agreements made during a meeting in Vancouver in
1987 by the International Steering Committee of Medical Editors.
• In-text citations (like in IEEE) the authors are numbered in the text in order of their
appearance, and the numbers are enclosed in square brackets.
Jasanoff [5] makes the point that the risk of cross-infection is growing.
References
(5) Jasanoff, M. Tuberculosis: A Sub-Saharan Perspective. New York: Schaffter (2001).
• The reference list is numbered sequentially, but the authors are listed surnames first,
followed by their initials. Again the dates of publications are given after journal titles, or
at the ends of the references for books etc. The key feature of the Vancouver style is its
‘spare’ typography and punctuation, and the use of abbreviated journal titles.
For example:
1 Zammuner VL. Individual and co-operative computer writing and revising: Who gets the
best results? Learn Instruc 1995;5 (Pt 2): 101–24.
2 Tang C. Effects of collaborative learning on the quality of assignments. In: Dart B,
Boulton-Lewis G, editors. Teaching and learning in higher education. Melbourne:
Australian Council for Educational Research, 1998;102–23.

11. The Chicago/Turabian style
A style guide for published works rather than class papers
• two different methods for documenting sources: the
Author-Date System and the Notes-Bibliography
(NB) System.
• Author-Date uses parenthetical citations in the text to
reference the source’s author’s last name and the year
of publication. Author-Date is very similar to APA
style.
• NB uses numbered footnotes in the text to direct the
reader to a shortened citation at the bottom of the page.
This corresponds to a fuller citation on a Bibliography
page that concludes the document. The citations
themselves are formatted differently from the way they
appear in Author-Date.

41. APA Reference List
APA is a complex system of citation. When compiling the reference
list, the strategy below might be useful:
1. Identify the type of source:
– Is it a book? A journal article? A webpage?
2. Find a sample citation for this type of source
– Check a textbook or the OWL APA Guide:
https://owl.purdue.edu/owl/research_and_citation/apa7_style/apa
_formatting_and_style_guide/general_format.html
3. “Mirror” the sample
4. Make sure that the entries are listed in alphabetical order and that
the subsequent lines are indented

42. APA Reference List

43. APA In-text Citation: Basics
• A parenthetical citation includes both the author’s last
name and year of publication, separated by a comma,
in parentheses at the end of the sentence.
Research suggests that the Purdue OWL is a good
resource for students (Atkins, 2018).
• A narrative citation includes the author’s name
directly in the sentence, with the year of publication
directly following the author’s last name.
Atkins (2018) suggests that the Purdue OWL is a
good resource for students.

44. APA In-text Citation: Page Numbers
• If the source you’re citing includes page numbers, add that
information to your citation.
For a parenthetical citation, the page number follows the
year of publication, separated by a comma, and with a
lowercase p and a period before the number (p.)
Research suggests that the Purdue OWL is a good
resource for students (Atkins, 2018, p. 12).
• For a narrative citation, the page number comes at the end
of the sentence, once again preceded by a lowercase p and a
period (p.)
Atkins (2018) suggests that the Purdue OWL is a good
resource for students (pp. 12-13).

45. APA In-Text Citation: Quotations
• Introduce the quotation with a signal phrase
• In the parenthetical citation, include the author, date of publication,
and page number at the end of the quotation.
As scientific knowledge advances, “the application of CRISPR
technology to improve human health is being explored across
public and private sectors”(Hong, 2018, p. 503).
• In the narrative-style citation, include the author’s last name in the
signal phrase, with the page number at the end of the quote.
Hong (2018) stated that “the application of CRISPR technology
to improve human health is being explored across public and
private sectors” (p. 503).

46. APA In-Text Citation: Summary or Paraphrase
• The same guidelines for parenthetical and narrative citations
when summarizing or paraphrasing a longer chunk of text.
• Parenthetical citation:
In one study that consisted of 467 young adults, it was found
that social media use may not directly affect mental health;
rather, it depends on how young adults use social media
(Berryman, Ferguson, & Negy, 2018).
• Narrative citation:
Berryman, Ferguson, and Negy (2018) sampled 467 young
adults about their social media use and mental health and
found that social media use may not directly affect mental
health; rather, it depends on how young adults use social
media.

47. APA In-Text Citation: Signal Words
• Introduce quotations with signal phrases, e.g.:
According to Reynolds (2019), “….” (p. 3).
Reynolds (2019) argued that“……” (p. 3).
• Use signal verbs such as:
acknowledged, contended, maintained,
responded, reported, argued, concluded, etc.
• Use the past tense or the present perfect tense of
verbs in signal phrases when they discuss past
events.

48. APA in-text citations examples

49. APA In-Text Citation: Two or More Works
• When the parenthetical citation includes
two or more works:
Order them in the same way they appear in the
reference list—the author’s name, the year of
publication—separated by a semi-colon.
Lorem ipsum dolor sit amet (Adams, 2018;
Collins, 2017).

50. APA In-Text Citation: Works with Several Authors
When citing a work with two authors:
In the narrative citation, use “and” in between the authors’ names
According to scientists Depietri and McPhearson (2018), “Understanding
the occurrence and impacts of historical climatic hazards is critical to
better interpret current hazard trends” (p. 96).
In the parenthetical citation, use “&” between names
When examining potential climate threats, “Understanding the occurrence
and impacts of historical climatic hazards is critical to better interpret
current hazard trends” (Depietri & McPhearson, 2018, p. 96).
When citing a work with three or more authors: list the name of the
first author plus “et al.” in every citation.
Lin et al. (2019) examined how weather conditions affect the popularity
of the bikesharing program in Beijing.
One study looked at how weather conditions affected the popularity of
bikesharing programs, specifically the Beijing Public Bikesharing Program
(Lin et al., 2019).

51. APA In-Text Citation: Unknown Author
When citing a work with an unknown author:
Use the source’s full title in the narrative citation.
Cite the first word of the title followed by the year of
publication in the parenthetical citation.
According to “Here’s How Gardening Benefits Your
Health” (2018)
(“Here’s,” 2018)
Titles:
Articles and Chapters = “ ”
Books and Reports = italicize

52. APA In-Text Citation: No Page Numbers
For parenthetical citation. Use any of the following four methods
•List the heading or section name
One scientist noted that “A cup full of kale can help your body out
in a number of ways” (London, 2019, Health benefits of kale section).
• List an abbreviated heading or section name in quotation marks (if the
heading is too long)
One scientist noted that “A cup full of kale can help your body out in a
number of ways” (London, 2019, “Health benefits” section).
• List the paragraph number
One scientist noted that “A cup full of kale can help your body out in a
number of ways” (London, 2019, para. 2).
• List the heading or section name and the paragraph number
One scientist noted that “A cup full of kale can help your body out in a
number of ways” (London, 2019, Health benefits of kale section, para. 2).

53. In narrative citation use any of the following four methods
• List the heading or section name
Scientist Jaclyn London (2019, Health benefits of kale section) noted that
“A cup full of kale can help your body out in a number of ways.”
• List an abbreviated heading or section name in quotation marks (if the
heading is too long)
Scientist Jaclyn London (2019, “Health benefits” section) noted that “A
