Literature review is an important part of academic research and is used in many fields. In this article, we will discuss what the literature review is, why it is important, the important points to be considered while searching the literature, the methods that can be used in the literature review, and finally the difficulties that can be encountered in the literature review and how to overcome them.
What is Literature Review?
Literature review is the process of collecting, examining and analyzing available written sources on a particular topic. These resources can be academic journal articles, books, dissertations, conference proceedings, and other academic publications. A literature review forms the basis of a study and provides a way for researchers to understand existing knowledge, refine their research, and identify new research questions.
Why Should We Do a Literature Review?
It is very important to conduct a literature review to increase the quality and validity of the research. By reviewing the literature, researchers can understand current knowledge and examine the results and methods of previous research. This provides researchers with an opportunity to understand existing knowledge and formulate research questions based on this knowledge before undertaking new research. In addition, by reviewing the literature, researchers can identify the deficiencies and gaps of existing studies and reveal the need for new research.
Points to Consider While Performing a Literature Review
While doing the literature review, there are a few important points to consider. These include:
Determination of subject boundaries: Before conducting a literature review, researchers should determine which subjects will be examined. This will help determine the scope of the research.
Using the right resources: It is important to use the right resources when reviewing the literature. Academic journals, books, theses, and other academic publications are considered accurate sources and should be used when searching the literature.
Analyzing sources: When scanning literature, it is important to analyze sources correctly. This will help researchers understand what the sources are about, evaluate the results, and compare the results with other sources.
Performing a comprehensive search: When searching the literature, it is important to perform a comprehensive search. This will help researchers find all relevant resources. It can be helpful to use different keywords and refer to different source databases when searching.
Literature Review Methods
Different methods can be used for literature review. These methods may vary depending on the type and objectives of the research. The most commonly used literature review methods are:
Systematic literature review: This method is a structured approach to collect, analyze and synthesize all available resources on a particular topic.
Traditional literature review: This is a more traditional approach to collecting available resources on a particular topic and creating a list for review.
Screening evaluation method: This method is an approach to evaluate the available scans on a particular subject and to determine the quality of the scans.
Difficulties Encountered in Literature Review and Their Solutions
While searching the literature, researchers may encounter some difficulties. These challenges may include finding the right resources, analyzing resources, and accessing different resource databases. To meet these challenges, researchers can find solutions using the right keywords, searching different source databases, and using different search strategies.
The literature review is an important step to ensure the success of the research. Finding the right resources, analyzing resources, doing a thorough search, and using the right methods can increase the quality and validity of research. Researchers can find the right resources and ensure their research is successful by using different strategies to overcome the challenges they face when searching the literature. On the other hand, there are some points to be considered while scanning the literature. One of them is to check the reliability and validity of sources. While searching the literature, researchers need to be sure about the selection of the right sources and the reliability and validity of these sources. It is also important to evaluate the history of the sources and the purpose for which the sources were used.
Researchers may also have difficulties accessing source databases. Accessing some resource databases may be chargeable or only available in certain countries. In these cases, researchers can expand their resources by using open-source databases, referencing libraries or the websites of scientific journals.
Literature review is a fundamental part of academic research and, when done correctly, increases the quality and validity of research. Finding the right resources, analyzing resources, doing a thorough search, and using the right methods are important components of literature review. Researchers can find the right resources and ensure their research is successful by using different strategies to overcome the challenges they face when searching the literature.
