What is literature review
A literature review thoroughly examines existing literature related to a specific topic, question, or area of study. It involves a systematic search, evaluation, and synthesis of existing knowledge about the subject matter, including essential concepts, theories, and empirical discoveries. The document elucidates the primary methodologies, approaches, or paradigms employed within the discipline, while also offering a comprehensive understanding of the research question or topic by considering the potential impact of various factors on the research. The text elucidates the chronology of the field or topic, shedding light on its historical progression, noteworthy findings, pivotal advancements, or transformative ideas. Additionally, it aims to recognize the main contributors including, scholars, or academicians who have made substantial contributions to the field.
Thus, it furnishes the reader with a complete knowledge of the subject matter and its inherent importance. It helps to establish the research context of the study within the existing body of literature, thereby enabling the identification of research gaps that have yet to be addressed. This, in turn, informs the development of research questions and objectives, which are crucial for guiding the overall direction of the study providing a framework for understanding the research findings and implications.
Types of Literature Review
A. Comprehensive Reviews: These reviews aim to provide a comprehensive overview of the literature on a particular topic, using a structured methodology to identify, evaluate, and synthesize the relevant evidence. These are further of following types:
1. Narrative Literature Review: A narrative literature review provides a comprehensive overview of the literature on a particular topic. It often uses a storytelling approach to describe the research findings, methods, and implications. This type of review is useful for providing background information or context for a research study.
Example: A review of the history of the development of the periodic table in chemistry, with special emphasis on key discoveries and contributions.
2. Meta-Analysis: A meta-analysis uses statistical methods to combine data from multiple studies to conclude a particular research question. It provides a quantitative summary of the results and can help to identify patterns and trends in the data. This type of review is useful for answering specific research questions and providing a comprehensive overview of the evidence.
Example: A meta-analysis of epidemiological studies on the relationship between particulate matter exposure and lung cancer risk.
3. Integrative Literature Review: An integrative literature review combines theoretical and empirical literature to provide a comprehensive understanding of a research topic. It integrates findings from multiple disciplines and identifies areas of convergence and divergence. This type of review is useful for informing research design and developing a comprehensive understanding of the research topic.
Example: A multidisciplinary review of the relationships between climate change, air pollution, and human health.
4. Systematic Literature Review: A systematic literature review uses a predefined protocol to identify, evaluate, and synthesize all relevant studies on a specific research question. It aims to minimize bias and ensure that all relevant studies are included. This type of review is useful for answering specific research questions and informing evidence-based practice.
Example: A systematic review of studies on the effectiveness of carbon capture and storage technologies in reducing greenhouse gas emissions. These can be further of two types:
B. Focused Reviews: These reviews focus on a specific aspect of a research topic, examining the strengths and limitations of existing research, theoretical frameworks, concepts, methods, and experimental designs.
1. Critical Literature Review: A critical literature review analyzes the strengths and limitations of existing research on a particular topic. It examines the methodological quality, validity, and reliability of the studies and identifies gaps in the literature. This type of review is useful for identifying areas for future research and informing research design.
Example: A critical review of the limitations and biases in studies on the environmental impacts of fracking.
