The APA in text reference is in the format (author, date). When directly quoting from a text you must include a page number in the citation as given in the examples below. Including page numbers in all other circumstances is not required however, it is best practice to do so when referring to part of a work (e.g. a paragraph or chapter in a book). When referring to an entire work that covers a single topic (e.g. a journal article) it is not required.
Where your source quotes or refers to another source, for example Unsworth refers to previous work by Halliday on linguistics, the citation might read thus:
Only Unsworth will appear in the Reference list at the end of your assignment
Your reference list should be ordered alphabetically by author and then chronologically by year of publication. The APA 6th style requires the references to be indented as illustrated below in the examples.
For instances of multiple articles with the same authors and years of publication, please check the APA publication manual or Academic Writer. If you have the DOI for the journal article, you should include it in the reference, otherwise, it is not necessary.
Academic Writer is APA's tool fully integrated with Publication manual of the American Psychological Association (6th ed.).
