Types of review of literature

It is important to think of knowledge in a given field as consisting of three layers.

• First, there are the primary studies that researchers conduct and publish.
• Second, are the reviews of those studies that summarize and offer new interpretations built from and often extending beyond the original studies.
• Third, there are the perceptions, conclusions, opinions, and interpretations that are shared informally that become part of the lore of the field.

In composing a literature review, it is important to note that it is often this third layer of knowledge that is cited as "true" even though it often has only a loose relationship to the primary studies and secondary literature reviews.

Given this, while literature reviews are designed to provide an overview and synthesis of pertinent sources you have explored, there are several approaches to how they can be done, depending upon the type of analysis underpinning your study. Listed below are definitions of types of literature reviews:

Argumentative Review
     This form examines literature selectively in order to support or refute an argument, deeply embedded assumption, or philosophical problem already established in the literature. The purpose is to develop a body of literature that establishes a contrarian viewpoint. Given the value-laden nature of some social science research [e.g., educational reform; immigration control], argumentative approaches to analyzing the literature can be a legitimate and important form of discourse. However, note that they can also introduce problems of bias when they are used to make summary claims of the sort found in systematic reviews.

Integrative Review
     Considered a form of research that reviews, critiques, and synthesizes representative literature on a topic in an integrated way such that new frameworks and perspectives on the topic are generated. The body of literature includes all studies that address related or identical hypotheses. A well-done integrative review meets the same standards as primary research in regard to clarity, rigor, and replication.

Historical Review
     Few things rest in isolation from historical precedent. Historical reviews are focused on examining research throughout a period of time, often starting with the first time an issue, concept, theory, phenomenon emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and to identify the likely directions for future research.

Methodological Review
     A review does not always focus on what someone said [content], but how they said it [method of analysis]. This approach provides a framework of understanding at different levels [i.e. those of theory, substantive fields, research approaches, and data collection and analysis techniques], enables researchers to draw on a wide variety of knowledge ranging from the conceptual level to practical documents for use in fieldwork in the areas of ontological and epistemological consideration, quantitative and qualitative integration, sampling, interviewing, data collection and data analysis, and helps highlight many ethical issues which we should be aware of and consider as we go through our study.

Systematic Review
     This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research, and to collect, report, and analyze data from the studies that are included in the review. Typically it focuses on a very specific empirical question, often posed in a cause-and-effect form, such as "To what extent does A contribute to B?"

Theoretical Review
     The purpose of this form is to concretely examine the corpus of theory that has accumulated in regard to an issue, concept, theory, phenomenon. The theoretical literature review help establish what theories already exist, the relationships between them, to what degree the existing theories have been investigated, and to develop new hypotheses to be tested. Often this form is used to help establish a lack of appropriate theories or reveal that current theories are inadequate for explaining new or emerging research problems. The unit of analysis can focus on a theoretical concept or a whole theory or framework.

There are many different types of literature reviews, each with its own approach, analysis, and purpose. To confuse matters, these types aren't named consistently. The following are some of the more common types of literature reviews.

These are more rigorous, with some level of appraisal:

• The Systematic Review is important to health care and medical trials, and other subjects where methodology and data are important. Through rigorous review and analysis of literature that meets a specific criteria, the systematic review identifies and compares answers to health care related questions. The systematic review may include meta-analysis and meta-synthesis, which leads us to...
• The Quantitative or Qualitative Meta-analysis Review can both make up the whole or part of systematic review[s]. Both are thorough and comprehensive in condensing and making sense of a large body of research. The quantitative meta-analysis reviews quantitative research, is objective, and includes statistical analysis. The qualitative meta-analysis reviews qualitative research, is subjective [or evaluative, or interpretive], and identifies new themes or concepts.

These don't always include a formal assessment or analysis:

• The Literature Review [see our Literature Review video] or Narrative Review often appears as a chapter in a thesis or dissertation. It describes what related research has already been conducted, how it informs the thesis, and how the thesis fits into the research in the field. [See //student.unsw.edu.au/writing-critical-review for more information.]
• The Critical Review is like a literature review, but requires a more detailed examination of the literature, in order to compare and evaluate a number of perspectives.
• The Scoping Review is often used at the beginning of an article, dissertation or research proposal. It is conducted before the research begins, and sets the stage for this research by highlighting gaps in the literature, and explaining the need for the research about to be conducted, which is presented in the remainder of the article.
• The Conceptual Review groups articles according to concepts, or categories, or themes. It identifies the current 'understanding' of the given research topic, discusses how this understanding was reached, and attempts to determine whether a greater understanding can be suggested. It provides a snapshot of where things are with this particular field of research.
• The State-of-the-Art Review is conducted periodically, with a focus on the most recent research. It describes what is currently known, understood, or agreed upon regarding the research topic, and highlights where are there still disagreements.
