A literature review is a comprehensive summary of all the information that has been prepared to date on a particular topic. When you decide on a research topic, write my essay often the first step towards doing research is to learn more about previous research published on the topic, and this eventually turns into a literature review as you write your research paper. The literature review is one of the pillars on which your research idea rests, as it provides context, relevance, and background to the research problem you are investigating.

Types of literature review

Literature reviews can be categorized as experimental and theoretical. Experimental literature review basically means searching all the available information on a given topic and critically analyzing the gaps that need to be worked on. In this sense, it essentially constitutes the first experiment of any research project. The more comprehensive the review, the more precise and systematic the research project will be. Therefore, it is one of the most critical parts of one's research.

The theoretical literature review essentially involves two steps:

Examining and critically reading the available literature: this step is often referred to as an empirical literature review.

Summarizing and really writing the gist of your regular review: This is known as the theory review.

A literature review can be part of a thesis or research paper and an independent literature review. Let's look at this in more detail;

Literature reviews for thesis/research paper

Every research report/dissertation/research paper begins with an introduction to the research topic. It constitutes the literature review for this article. The main purpose of the review is to introduce readers to the need to conduct said research. A literature review, Google Scholar, do my essay PubMed, etc. It should begin with a thorough literature review using key keywords from relevant online databases such as Once all relevant literature has been collected, it should be organized as follows:

Background literature on the broad research topic to introduce readers to the field of study.

Recent advances in work can be organized thematically or chronologically. Ideally, separate themes should be discussed in chronological order to explain how research in the field has evolved and to highlight progress in the field.

The review should include a comparison and contrast of different studies. Discussing controversial aspects helps identify key gaps that need to be worked on. This is necessary to define the problem statement of the study and to emphasize the importance of the research in question.

Once a problem statement has been defined, the strengths and pitfalls of other studies that have addressed the problem statement should be discussed. This is important for outlining the need and innovation of research.

A literature review should not be just a narrative of all available information. There should be a critical and analytical summary of the selected literature that guides readers through the main theme of the research.

Independent literature reviews

Literature reviews can also be written as independent articles. These are no different from the literature review sections described above; however, they are not followed by experimental data.

They fall into 2 broad categories: narrative studies and systematic reviews.

1. Narrative studies

These are theoretical discussions and critical analyses of information on a particular topic. These are mostly qualitative, similar to the review sections of larger articles.

Narrative reviews are usually organized as follows:

Introduction that determines the context of the research area and the subject of study

The body is normally used to describe different themes under the main heading by dividing them into different subheadings. This section compares and contrasts published studies and identifies gaps that have not been addressed or have been unsuccessfully addressed.

Results. This section differs slightly between reviews that are part of research papers and narrative reviews. This section describes the main results from the analysis of all current studies and sets out other avenues for research. This section requires critical commentary by the author for the review to add value to the existing literature. It should come up with ideas/hypotheses that can explain any inconsistencies and provide solutions to existing problems.

2. Systematic reviews

On the other hand, systematic reviews follow a well-planned methodology to analyze a certain number of studies qualitatively or quantitatively. They usually focus on a single question and have clear study objectives that are systematically worked out. These studies are based on a well-defined strategy as opposed to narrative studies. Systematic reviews and narrative reviews are organized somewhat differently. It usually develops like this:

Introduction: Systematic reviews begin with specific research questions defined in terms of examples to be examined and research outputs.

Methods (for systematic reviews only): These studies have a comprehensive methodology that begins by narrowing the literature for review. Usually, specific inclusion/exclusion criteria are determined by the research questions, and databases are searched according to these criteria. After the case studies are shortlisted, they are analyzed in detail.

Results: The results section of these studies includes extensive data analysis to determine the significance of the study results. Systematic reviews may be accompanied by Meta-analysis, which includes statistical analysis of included studies to increase the power of results.

Discussion: This section generally interprets study data in terms of weighted significance and strength of results. The study, therefore, provides enhanced results that are validated by the scientific rigor of the analytical method.

Before you start writing a review, it's important to determine what type of review you want to write and follow the appropriate style and guidelines. An effective literature review is essential for the entire life cycle of research,  write my essay for me from defining the right research objectives to the correct interpretation and presentation of research results.
