A source citation is placed in your text at the time you refer to a work by another author(s), as a paraphrase or quote. A citation is a short reference in the text to a full description of that source in the reference list.

An in-text citation is the same for all types of sources and consists of author (WHO), date (WHEN) and page number(s) if any.

            WHO                 WHEN

All other details of the source consulted are included in the reference list.

From the in-text citation, the reader cannot yet tell what type of source it is, so the reader must look up the source in the reference list.

An in-text citation is part of a sentence and can be placed at the beginning, halfway or at the end of the sentence.

You decide where the citation is placed, as long as it is clear to the reader which part of the text is your own work and which part is based on another source.

In-text citations can appear in two formats: parenthetical and narrative.

• In parenthetical citations, the author name and publication date appear in parentheses.

• In narrative citations, the author name is incorporated into the text as part of the sentence and the year follows in parentheses.

It can be distracting for the reader if the text is interrupted by the same source citation each time.

Tip: If you are basing a chapter in your report on a research method from a book and you are using a paraphrase, it is better to mention it at the beginning of the text, for example:

Please note: 

- if you are going to cite during the writing of that chapter, then the page numbers must be listed separately,

- if you cite another source in this chapter, then the earlier source must be cited again, so that there can be no doubt as to which source you are referring to.

You always name one or two authors (or editors) when you paraphrase or quote.

How a reference should (exactly) look like in the text is determined by the structure of the sentence. For example, you can:

• cite the author in the text, and place the year in parentheses

•  Place both authors and year in parenthesis (separate author name and year with a comma)

•  mention authors and year both in the text (however, this is less common).

If you refer to the same source several times within the same paragraph, you do not need to mention the year again after the first reference, at least if you named the author in the text.

In case of three or more authors, mention only the first name with the addition et al. (Latin abbreviation for et alii, "and others"). Example:

• parenthetical citation

• narrative citation

Tip: See also Paragraph 8.17 of the Publication Manual of the APA. 

Prefixes as 'van' or 'de' are part of the surname. Include them, keeping the spacing and their preferred capitalization.

For example:

• Leonardo Del Vecchio would be Del Vecchio, L.
• Simone de Beauvoir would be de Beauvoir, S.

 (Del Vecchio, year)

(de Beauvoir, year)

In the reference list, surnames with prefixes are alphabetized by the first letter of the prefix.

Separate references to two or more works by different authors with a semicolon. Place references in alphabetical order (i.e., the same order as in the bibliography).

• Organization as author

If no personal name is listed as the author, the responsible organization is listed.

In the second reference, you may use an abbreviation, as long as it is well established or readily apparent. You introduce the abbreviation as follows: 

- When the name of the organization is mentioned in the running text, you mention the abbreviation (in round brackets) after the full name of the organization.

- If the full name of the organization is in round brackets, put the abbreviation in square brackets.

- In the following reference(s), the abbreviation is sufficient.  

• No author or organization

If there is no author or organization, the title is mentioned. If the title is long, it may be shortened to the first few words.
