Frankly, I don't use this style in writing my papers and this is the first time. Yesterday, I was try to looking for about the meaning of abbreviation (APA) and I found that it means (Association Psychological American). That's not all, I was found this link that supports writing references in this style.
H! In my articles, I seldom have to use anything else than APA style referencing. A practical shortcut to a reference in APA style is to google for the source in Google Scholar, click on the big citation mark below the right publication found. Then a window shows up with the reference in APA, MLA and ISO690, and downloadable small files for BibTex, Endnote etc. Just copy the APA style ref - but check it first. Not always perfect.
