1) Introduction The introduction should identify your topic, some discussion of the significance of that topic and a thesis statement that outlines what conclusion you will draw from your analysis and synthesis of the literature. If your literature review is part of a larger work, explain the importance of the review to your research question.2) Body In the body, discuss and assess the research according to specific organizational principles (see examples below), rather than addressing each source separately. Most, if not all, paragraphs should discuss more than one source. Avoid addressing your sources alphabetically as this does not assist in developing the themes or key issues central to your review. Organizing Principles Principle When to Use Example Theme -When explaining key themes or issues relevant to the topic -This is the most common way to organize literature reviews. A literature review of 31 relevant articles published between January 1999 and March 2004 identified 12 categories of neighborhood characteristics relevant to maternal and child health: income/wealth, employment, family structure, population composition, housing, mobility, education, occupation, social resources, violence and crime, deviant behavior and physical conditions. [Example adapted from Rajaratnama, J.K., Burke, J.G. & O’Campo, P. (2006). Maternal and child health and neighborhood context: The selection and construction of area-level variables. Health and Place, 12, 547-556.] Methodology (also called a methodology review) When discussing interdisciplinary approaches to a topic or when discussing a number of studies with a different approach. In dentistry, fluorescent imaging been used for many applications revealing a variety of information about bonded restorations. This review evaluates the different methods used in this area with the intent of determining if standardized methodologies exist. [Example adapted from D’Alpino, P.H.P. et al (2006).Use of fluorescent compounds in assessing bonded resin-based restorations: A literature review Journal of Dentistry, 34 623-634.] Chronology When historical changes are central to explaining the topic. A literature review is presented on the evolution of water pollution management and its impact on land pollution from 1900 to 2000 within a hypothesis of whether we could have done more, sooner. Stream pollution science in the context of the fundamental sanitary engineering concepts of reasonable use and assimilative capacity is examined in light of evolving regulatory frameworks from the early 1900s, when regulation and standards were mostly lacking, to the zero discharge goals and comprehensive federal command/control regulations of the late 20th century. [Example adapted from Shrifin, N.S. (2005). Pollution Management in the Twentieth Century. Journal of Environmental Engineering, 131, 676-691.] 3) Conclusion The conclusion should provide a summary of YOUR findings from the literature review. Explain what your analysis of the material leads you to conclude about the overall state of the literature, what it provides and where it is lacking. You can also provide suggestions for future research or explain how your future research will fill the gaps in the existing body of work on that topic.
