Book in translation

In general, you don't need to include the translator of a publication. However, when it comes to works where the translator is of importance concerning the interpretation of the work, this can be included, for example in philosophical works and fiction. You can also include the year the work was originally published, especially if there is a big difference between the original work and the translation. 

In-text citation:

If you have the originally published year included in the references, write both the published year and the originally published year in the in-text citation in the following way: 

  • (Laplace, 1814/1951)
  • Laplace (1814/1951) stated that ...

In the reference list:

Author, A. (year). Title (Translator initials. Translator last name, Trans.). Publisher. (Original work published Year)
