The new edition of the Publication Manual of the American Psychological Association was published in 2009. If you are used to using the previous APA style manual, your teachers will expect you to know the changes.
Remember the running head in the text section of the title page? You can forget about it. The editors decided that there was no need for it. However, the running head in the header is still required, but it is placed on the left side of the header. The page number remains at the right margin.
In the former APA manual, only one space was allowed after the period or whatever punctuation ended the sentence. This was an economical use of paper and saved many trees. Now, two spaces are required instead of one, because it looks better. In the past, you could choose from two fonts: New Times Roman or Courier. Now there is no choice. It’s New Times Roman.
The heading format has also changed. Headings are centered and boldface. Subheadings are flush left and boldface. Looking at the sample paper provided on the APA Style website will help you understand the headings format.
After the traditional order of the title page, abstract, and text, the new order of the next sections are references, tables, figures, appendices.
You will not need to include as much information in your references for electronic books. After you list the author, publication date, and title, only the source of the ebook is required. If you found the ebook at NetLibrary, you would list NetLibrary’s URL.
Using the former edition, you were required to give your retrieval date for web site articles. Currently, if the article is unlikely to change, you do not need to give the retrieval date. But if the article is likely to change, include the retrieval date.
Use a doi (digital object identifier) to reference journal articles from databases. The doi should be located near the article. You do not name the database or the retrieval date. If you cannot find a doi for the article, cite the web site of the publisher of the print periodical. For example, the publisher’s web site for the periodical African Affairs is the URL for Oxford Journals.
