This guides provides only a brief introduction to referencing in the APA style.  Please refer to the Publication Manual of the American Psychological Association, 6th edition, for more information. There are 2 variations from the Manual as used at UWA.  These were arrived at in consultation with the UWA School of Psychology.  They are:

• If no DOI (digital object identifier) is assigned and the article or e-book is retrieved from a database, include the name of the database in the reference list entry. There is no need to establish if the item is only available from that database or to look for the URL of the journal or book's own web site.
• Include the journal issue number if available.  There is no need to check if the journal paginates by volume or by issue.

Notes:

• When recording the DOI the URL format is preferred at UWA  e.g. http://dx.doi.org/10.1037/a0024996 
• With the 6th edition, retrieval date is no longer required for online materials except for sources which have very volatile content e.g. wikis.

If you need to refer to a work that has been cited in a paper you have read but which you have not read yourself then the cited work is only referred to as part of the in-text citation.  The reference list entry is for the paper you have read.
