Some publications give their articles a Digital Object Identifier (DOI) number, to help identify the article. These numbers can usually be found on the article abstract page, or on the title page of the article. Some articles do not have a DOI number.

In-Text Citations
In-text citations in APA list the author and the date of publication in parentheses at the end of the sentence, before the period. For example, there is an in-text citation at the end of this sentence (Author, 2010). If you are citing a direct quote or another specific part of a source, you'll want to get more specific by adding page numbers. There's another example at the end of this sentence (Author, 2010, p.5).
Reference List
Your APA Reference List should be a separate page (or pages) at the end of your paper, titled "Reference List." List your sources alphabetically by the author's last name. Below are some examples of APA citations of different source types.
