Entries in encyclopedias and dictionaries

Läs den här sidan på svenska

The instructions on this page concern references to entries in encyclopedias and dictionaries. Some encyclopedias/dictionaries will have a group author, e.g. organization or company, instead of a personal author. If the publisher is the same as the group author, omit the publisher from the source element. If the encyclopedia/dictionary does not have an editor, leave out this part and simply state "In" followed by the title of the encyclopedia/dictionary. For entries in online encyclopedia or dictionary, include the month and day in the publication date if available. If the online reference work is continously uppdated and the versions are not archived, state "n.d." as the year of publication and conclude the reference with information on the retrieval date in addition to the URL. 

If a DOI has been assigned to the encyclopedia/dictionary, include this number in the reference. If no DOI has been assigned and the encyclopedia/dictionary was accessed online from a nondatabase website, use the URL of the webpage from which it was retrieved. If the encyclopedia/dictionary was accessed in print or retrieved from an academic database, no URL is included.

Do not forget to consult the general instructions on how to write references according to APA (7th edition), including
