Purdue OWL provides extensive information on producing written text that conforms to the style guidelines of the American Psychological Association. APA rules include guidelines on formatting written work, making in-text citations, providing footnotes and endnotes, and listing reference sources.
Written material in the social sciences, including psychology, economics and sociology, usually conforms to APA style guidelines that ensure textual consistency and uniformity. Written texts contain four major parts: the title page, abstract, main body and references. The title page includes the title, author's name and institutional affiliation. The title also appears as a running head at the top of each subsequent page. The abstract on the second page consists of a single paragraph that succinctly summarizes the main points of the article or research. The main body contains in-text citations that must document all materials that the writer refers to directly or indirectly.
Purdue OWL offers extensive information on properly citing these sources, including books, articles, websites, online data sets, photos and movies. Texts must end with a separate reference list that includes all the information readers need to locate every source cited in the text. The entries in the reference list must include every source used by the writer; in addition, the writer must cite every entry in the text itself. Finally, Purdue OWL discusses APA stylistic guidelines concerning point of view, avoiding bias, clarity, conciseness and word choice.
