APA Citation Guide

APA citation

APA style is one of the most common formats for citing sources Other well known citation styles include MLA and Chicago. This citation guide will help you cite sources flawlessly and efficiently in APA format.

APA citations consist of two parts:

  1. In-text citation: brief citation included in the sentence where the information is used. The in-text citation only contains the author’s last name and year of publication, e.g. (Smith, 2019). It identifies and helps locate the full source in the reference list.
  2. Reference list entry: full publication details listed alphabetically on the reference page, which appears right after the main body. The reference provides all information that is required to find the source, e.g. Smith, P. (2019, April 18). Citing Sources in APA Format.

APA in-text citations

An in-text citation is a concise way to show the reader where the original idea came from and to give credit to the original author.

According to the APA citation guidelines, you should write down the last name of the author(s) and the year of publication. When quoting a source it is also required to include the page number(s). This can be done in multiple ways:

  • An earlier study in which X and Y were compared revealed that … (Smith, 2017).
  • Smith (2017) shows how, in the past, research into X was mainly concerned with …
  • In 2017, research was carried out by Smith that indicated that …

Multiple authors

When there are two authors, separate their last names with an ampersand.

When there are three or more authors, separate their last names using commas. The last two authors’ last names should be separated by both a comma and an ampersand (in a citation) or “and” (in the running text).

Two authors

  • Research shows that there is a great need for … (Reynolds & Thomas, 2014).
  • Reynolds and Thomas (2014) write that there is a great need for …

3-5 authors

  • Recent research suggests that there is … (McGuire, Morrison, Reynolds, & Thomas, 2014).
  • McGuire, Morrison, Reynolds, and Thomas (2014) argue that …

As you can imagine, citing a source with 3–5 authors takes up a lot of space in the text.

That is why you shorten the citation when you use the source a second, third or fourth time.

How? Instead of writing down all authors’ last names, write only the last name of the first author, followed by “et al.,” which means “and others.”

  • In this research, many participants made use of … (McGuire et al., 2014).
  • McGuire et al. (2014) noticed that …

6 or more authors

When your source has six or more authors, simply use the last name of the first author followed by “et al.” in your in-text citation:

  • Lunott et al. (2015) see the …

Organization as author

When the source is published by an organization instead of a person, cite the organization’s name as the author.

  • According to new research … (Microsoft, 2014).

Quotes

When you copy an excerpt of a text from another source and place it between quotation marks, you are quoting. When you quote sources, you are required to add the page number to the in-text citation.

  • This is also true from the business plan: “making an APA Citation Generator is a lot of work, but many students benefit from it” (Swan, 2014, p. 5).

Multiple sources in one citation

Sometimes, it’s necessary to cite multiple sources in one sentence. You can do this by citing multiples sources and separating them using semicolons.

  • Various studies show that … (Docker & Vagrant, 2002; Porter, 1997; Lima, Swan, & Corrieri, 2012).

Full in-text citation guide

APA reference page

The APA reference page, included after the main text, contains the full reference of all sources cited in the text. Sources are ordered alphabetically based on the author’s last name (or on the title for sources with no author).

The reference format differs depending on the source type (e.g. a website, journal, book). The format also changes when information about a source is missing (e.g. an unknown author or publication date) or when information is added (e.g. a second edition book).

APA formatting

There are certain formatting rules you must adhere to when writing a paper in apa format.

The basic requirements are:

  • Text must be double-spaced
  • Margins must be set to one inch (or 2.54 cm)
  • You must use a left-aligned running head with a shortened title on all pages
  • It is strongly recommended to use Times New Roman in 12 pt (if your university allows it, you might be able to use a different font)

In addition to these general rules that apply for every part of an APA style paper, each section has its own requirements. Learn about the requirements by looking at the interactive formatting examples of the title page, running head, abstract, reference page and headings and subheadings.

Avoid plagiarism

Plagiarism means copying someone else’s work, without giving that author credit. This is not only unfair for the original author, but also considered cheating which can have severe consequences.

Tips for avoiding plagiarism:

  • Save your sources. This way, you can keep track of them. You don’t necessarily have to have the citation perfectly formatted from the beginning.
  • When you quote or paraphrase text, temporarily highlight it to remind yourself that you need to add the correct citations.
    Check whether you’ve cited all your sources correctly, both in the text and in the reference list.
  • Quote, paraphrase and summarize other’s work correctly.
  • Run a plagiarism checker.

Where do I put citations in my text?

If you use several sources, you should refer to them frequently in your text. The basic rule is that it is better to refer to sources too much than too little.

Readers of your thesis should know at a glance if the information you are presenting is taken from a source.

What do I do if information is missing?

You may find that you don’t have all of the information normally required for a citation, particularly if you are using internet sources. If this happens, just skip those fields in the APA Generator. The citation will be generated for you in the correct manner.

See examples of sources that are missing a title, publication date or author.

What do I do with a source within a source (indirect reference)?

If you want to refer to a source that is included in another source, we recommend that you try to track down the original source. If you find it, you can then just cite it following the normal APA rules.

If you cannot find that original source, you should cite it through the source that mentioned it. This is called making an indirect reference or citing a secondary source.

Within your text, you then need to mention both authors.

Example: Driessen (in Swaen, 2014) uses three methods.

If one author has quoted another author, you need to add “as cited.”

Example: Driessen (in Swaen, 2014) describes three methods.

Can I translate a quote from a source?

If you want to use a translation of a quote, the APA Style says that you should treat it as paraphrased text – not a quote.

In this case, follow the regular rules for paraphrasing and don’t use quotation marks. In your reference list, write the original title followed by the translated title in square brackets: [x].

How do I cite several publications from different authors?

Write the citations in alphabetical order, separated by semicolons and spaces.

Example: Several studies (Driessen & Anterveld, 2002; Swaen, 1997; Van Laak, 2011) show…
