APA Style Sheet


APA (American Psychological Association) Style is a system of documentation that is used for both scholarly manuscripts and research papers. The style sheet (as it is often called) will provide you with specific instructions on all matters of documenting information retrieved from books, magazines, newspapers, scholarly journals, and electronic resources. This information will appear in your References, which is a list of the works cited in your paper. You must follow specific instructions when citing information from a book, a periodical (meaning a magazine, newspaper, or academic journal), a Web site, or an online database. Below are some examples.
