Referencing a quotation

Indeed, one researcher commented that “technological innovations have saved or extended the lives of many patients” (Lumby, 2001, p. 44).

If the quotation is over 40 words, you must indent the entire quotation and start the quotation on a new line. No quotation marks are required. Cite the quoted source after the final punctuation mark.

Citing translated sources in APA style

Here’s how you would cite the original French edition of a work by Piaget (note that an English translation of the title is included in brackets):

Piaget, J. (1966). La psychologie de l’enfant [The psychology of the child]. Paris, France: Presses Universitaires de France. 

Here’s another example, from a German journal. Again, brackets contain an English translation of the work’s title (the article, not the journal).

Janzen, G., & Hawlik, M. (2005). Orientierung im Raum: Befunde zu Entscheidungspunkten [Orientation in space: Findings about decision points]. Zeitschrift für Psychologie, 213(4), 179–186. doi:10.1026/0044-3409.213.4.179

If you read an English translation of a foreign work, by including translator:

Piaget, J. (1969). The psychology of the child (H. Weaver, Trans.). New York, NY: Basic Books.


Your reference list should be in English. Do not use non-English titles and non-English characters. If a source is not available in English, that is, if it does not have an English title, write the original title then add its English translation in square brackets.

Grangeat, M. (2011) (Ed.). Les démarches d’investigation dans l’enseignement scientifique Pratiques de classe, travail collectif enseignant, acquisitions des élèves. Ecole Normale Supérieure.

should be written as,

Les démarches d’investigation dans l’enseignement scientifique Pratiques de classe, travail collectif enseignant, acquisitions des élèves [Investigative approaches in science teaching class practices, collective teacher work, student acquisitions]. Ecole Normale Supérieure.

Here is an example of an article in a journal.
