Review articles provide an evaluation of research on a topic and are a useful starting point for researchers.
Some journals focus on review articles. e.g. Annual review series, whilst other journals may contain some review articles as well as research studies.
Most subject databases have an option to limit a search to review articles by using the limit option under Publication Type. You might also limit to Systematic Reviews.
Following are some examples of review journals:
A literature review is an evaluation of relevant literature on a topic and is usually the starting point for any undergraduate essay or postgraduate thesis. The focus for a literature review is on scholarly published materials such as books, journal articles and reports.
A search and review of relevant sources may be extensive and form part of a thesis or research project. Postgraduate researchers will normally focus on primary sources such as research studies in journals.
A literature review also provides evidence for an undergraduate assignment. Students new to a discipline may find that starting with an overview or review of relevant research in books and journals, the easiest way to begin researching a topic and obtaining the necessary background information.
Source materials can be categorised as:
Primary source: Original research from journals articles or conference papers, original materials such as historical documents, or creative works.
Secondary source: Evaluations, reviews or syntheses of original work. e.g. review articles in journals.
Tertiary source: Broadly scoped material put together usually from secondary sources to provide an overview, e.g. a book.
The Literature Review Structure:
Like a standard academic essay, a literature review is made up of three key components: an introduction, a body and a conclusion. Most literature reviews can follow the following format:
• Introduction: Introduce the topic/problem and the context within which it is found.
• Body: Examine past research in the area highlighting methodological and/or theoretical developments, areas of agreement, contentious areas, important studies and so forth. Keep the focus on your area of interest and identify gaps in the research that your research/investigation will attempt to fill. State clearly how your work builds on or responds to earlier work.
• Conclusion: Summarise what has emerged from the review of literature and reiterate conclusions.
