Elements of source references in APA style

Source citations in APA style are called references. References contain the following four elements:
- Author. This can be a person, group of people, or an organization. Use & for multiple authors. If there is no author, start the entry with the title.
- Date. Refers to the date of publication and is most commonly the year or an exact date, such as year, month, and day. Use (n.d.) for no date.
- Title. This can be either a work that stands alone, such as a book, or part of a greater whole, such as a journal article, and should always be in sentence case.
- Source. Indicates where readers can retrieve the cited work and could be a publisher or the title of a greater whole, such as a journal article and the journal name.
