Citations can be of two types: works cited page (MLA) or reference list (APA). Both include all of the information your reader needs to locate your source. However, there is a difference between how they are presented. With works cited pages, each citation includes the author's last name, year published, title of book/article/report, and page number. The reference list is exactly that--a list of references with only their journal title, volume number, and page numbers. Works cited pages are useful when you want to refer back to specific sources such as books by authors or articles in journals. Readers can use this page to find out more about the topic being discussed in order to better understand its relevance to their own work or project. In addition, it allows readers to see what other sources have been used by others in discussing the same topic. Reference lists are required for papers that use multiple sources for support, such as essays, reports, and chapters in books. Careful attention must be paid to ensure that each source listed in the reference list has been properly cited. Failure to do so may result in your paper being rejected due to lack of compliance with APA guidelines. References should be placed at the end of your paper, followed by any appendices.
