The American Psychological Association (APA) style is a widely used citation style for academic writing in the social sciences, including psychology, education, and business. In APA style, references to books should be listed in a separate section at the end of the paper, titled "References." This page should be organized alphabetically by the last name of the first author of each reference.
Here is an example of how to format a book reference in APA style:
Author, A. A. (Year). Title of work. Location: Publisher.
For example, if you were citing the book "The Catcher in the Rye" by J.D. Salinger, your reference would look like this:
Salinger, J. D. (1951). The catcher in the rye. New York, NY: Little, Brown and Company.
If the book has more than one author, list the authors in the order in which they appear on the title page of the book. For example, if you were citing the book "The Art of War" by Sun Tzu and translated by James Clavell, your reference would look like this:
Tzu, S., & Clavell, J. (1997). The art of war. Boston, MA: Shambhala.
If the book has more than seven authors, list the first six authors followed by an ellipsis (...) and the final author. For example, if you were citing the book "Psychology: An Introduction" by Charles G. Morris, Albert A. Maisto, and a team of eight other authors, your reference would look like this:
Morris, C. G., Maisto, A. A., & Authors, T. O. (2018). Psychology: An introduction. Upper Saddle River, NJ: Pearson.
It is important to note that the reference list should include only those sources that you have actually cited in your paper. Additionally, be sure to double-check that all of your references are formatted correctly and in alphabetical order. Proper citation is not only a way to give credit to the original authors of the ideas you are using, but it also helps to establish the credibility of your own work.
