The American Psychology Association (APA) style is designed for the social & life sciences (e.g. psychology, anthropology, medicine). These examples are adapted from the Publication Manual of the American Psychological Association. The print edition is located in the citation manual collection by the reference desk (Call number: Reference BF 76.7 .C66 2005, p177-190).
You will need to cite your sources in two places within your paper: in-text and bibliography
Part I outlines how to cite a source in the paragraph where you have quoted, summarized, or paraphrased from the source (called an in-text citation)
Part II outlines how to create an list of references, known as a bibliography, at the end of your paper that lists anything you cite.

You must cite the source of either a quotation or paraphrased material, regardless of the type of source: book, magazine or journal article, newspapers, etc. The APA uses the author-date method of citation; that is, the last name of the author and the year of publication are inserted in the text at the appropriate point.
