APA Referencing Style

APA style is a format for academic documents such as journal articles and books. It is codified in the style guide of the American Psychological Association (APA), titled the Publication Manual of the American Psychological Association. The APA states that the guidelines were developed to assist reading comprehension in the social and behavioral sciences, for clarity of communication, and for "word choice that best reduces bias in language". APA style is widely used, either entirely or with modifications, by hundreds of other scientific journals (including medical and other public health journals), in many textbooks, and in academia (for papers written in classes). The sixth edition of the Publication Manual of the American Psychological Association was released in July 2009 after four years of development.
