1. A reference citation provides authoritative sources for statements in a paper and acknowledges that information did not originate with the writer. It follows APA style, which uses author-date citations in text and a reference list of only cited sources.
2. APA style does not require footnotes; citations in text and a reference list provide enough information for readers to locate sources. The reference list is ordered alphabetically and includes pertinent details for different source types such as books, journal articles, websites, and more.
3. Electronic sources require a title, date, URL or DOI, and author if available when cited in APA style. Journal articles include a DOI if available rather than a URL or database name
