As part of their research program, many students are instructed to perform a literature review, without always understanding what a literature review is. Most are aware that it is a process of gathering information from other sources and documenting it, but few have any idea of how to evaluate the information, or how to present it. A literature review can be a precursor to the introduction of a research paper , or it can be an entire paper in itself, acting as the first stage of large research projects and allowing the supervisor to ascertain that the student is on the correct path. A literature review is a critical and in depth evaluation of previous research.
Usually, a literature review can be described as an objective, concise, and critical summary of published research literature pertinent to the subject being researched in an article. A literature can be an end in itself an analysis of what is known about a topic or a prologue to and rationale for engaging in primary research. Organize the literature review around key topics of concepts. Use headings or topic sentences to convey your organizational principle. Use a summary to assist the reader to relate every section to the wider topic and to clarify your argument's movement.
The relationship between socioeconomic status and health: a review of the literature
A literature review summarizes and synthesizes the existing scholarly research on a particular topic. Literature reviews are a form of academic writing commonly used in the sciences, social sciences, and humanities. However, unlike research papers, which establish new arguments and make original contributions, literature reviews organize and present existing research.
Please check course or programme information and materials provided by teaching staff , including your project supervisor, for subject-specific guidance. A literature review is a piece of academic writing demonstrating knowledge and understanding of the academic literature on a specific topic placed in context. A literature review also includes a critical evaluation of the material; this is why it is called a literature review rather than a literature report. To illustrate the difference between reporting and reviewing, think about television or film review articles. Similarly the two main objectives of a literature review are firstly the content covering existing research, theories and evidence, and secondly your own critical evaluation and discussion of this content.
