Structure of a Literature Review

Just how to structure a literature review: Like a number of other types of academic writing, a literature review follows a typical intro-body-conclusion style with 5 paragraphs overall. Now, let’s look at each component of the fundamental literature review structure in more detail:

INTRODUCTION

You need to direct your reader(s) towards the MOP (main organizing principle). Which means that your information must start from a wide perspective and gradually narrow down until it reaches your center point.

Start with presenting your overall concept (Corruption, for example). After the initial presentation, narrow your introduction’s focus towards the MOP by mentioning the criteria you used to select the literature sources you have chosen (Macbeth, All the King's Men and Animal Farm). Finally, the introduction will end with the presentation of your MOP that should directly link it to all three of the sources of literature.

Body paragraphs

Broadly speaking, each human body paragraph will focus on a particular source of literature laid out in the essay’s introduction. As each source has a unique frame of reference for the MOP, it is crucial to structure the review in the most logically consistent way possible. Which means the writing should either be structured chronologically, thematically, or methodologically.

Chronologically

Deteriorating your sources based on their publication date is a solid way to keep a correct historical timeline. If applied precisely, it can present the development of a specific concept with time and provide examples in the form of literature. However , sometimes there are better alternatives we could use to structure the human body.

Thematically

In the place of taking the “timeline approach”, another option can be taking a look at the link betwixt your MOP along with your sources. Sometimes, the main idea will just glare from the piece of literature. Other times, the author might have to seek out examples to prove their point. An experienced writer will usually present their sources by order of strength. For example , in “To Kill A Mockingbird”, the entire novel was centralized around racism; in “The Adventures of Huckleberry Finn”, racism was one of many themes.

Methodologically

As made obvious by the terminology, this sort of structuring targets the methods used to present the central concept. For example , in “1984”, George Orwell uses the law-and-order approach and shows the dangers of a dystopia for a social species.

In “Frankenstein”, Mary Shelley exposes the character’s physical faculties as repulsive and horrifying, forcing him to suffer in an isolated environment. By showcasing the different methods used to portray the MOP, the writer can compare them centered on things like severity, ethicality, and overall impact.

conclusion

After presenting your findings within the body paragraphs, you will find 3 final objectives to accomplish in the essay’s conclusion. First, the author should summarize the findings they've made or found in other words, and briefly answer comprehensively the question: “What maybe you have learned? ”

After discussing that information, the next phase is to present the value of the data in mention of the our current world today. In other words, just how can the reader take the data and apply it to today's society? From the period, we complete with a breadcrumb trail.

Whilst the author, you wish to leave the readers’ trail of thought within the actual essay topic. This gives them with a means of further investigation—meaning that the reader might consider where the discussion will go next.

Writing an Outline for a Literature Review

Students often underestimate the importance of planning the structure of these papers beforehand. However , this isn't a wise approach. Having a rough APA literature review outline (or other style outlines) will not only assist you to follow the proper format and structure, but will also make the writing process simpler and help ensure that you include all of the important info without missing anything.

How exactly to write a literature review outline: As you already know from the Structure section of this guide, all of your literature review performs its own crucial role. Respectively, you should create your outline while keeping the overall introduction-body-conclusion structure in mind and ensuring that each section meets its own objectives. However , you will need to remember that a literature review outline is slightly not the same as outlines of other types of essays since it does not provide new information. It is targeted on existing studies relevant to the primary topic.

Listed here is a literature review outline example on the subject of the Ebola virus to help you get it right:

  • INTRODUCTION
  1. Introduce the general topic. Provide back ground information on the Ebola virus: genome, pathogenesis, transmission, epidemiology, treatment, and so forth
  2. Shape the main research question: What's the potential role of arthropods (mechanical or biological vectors) in the distribution of the Ebola virus?

  4. Expected outcomes
  5. Over all trends in the literature on this topic: While the natural reservoir of the virus remains not known with certainty, many researchers genuinely believe that arthropods (and fruit bats, in particular) pay an important role in the distribution of herpes.
  • Body
  1. Subject 1: A short history of the specific piece of literature in general terms; an analysis of the important thing aspects of the research; a review of the investigation questions, practices, procedures, and outcomes; and an overview of the strong and flaws, gaps, and contradictions.

How to Write a Good Literature Review

Whether you are writing a literature review within the framework of a sizable research project (e. g. thesis, dissertation, or other) or as a stand-alone assignment, the approach you should decide to try writing generally speaking remains the exact same.

Now, as you know in regards to the general rules and have a fundamental literature review outline template, let’s define the steps to decide to try handle this right:

Step 1: Identifying the Topic

That is probably the only matter you might approach differently depending on whether your literature review comes within a research paper or perhaps a separate assignment altogether. If you're creating a literature review as part of another work, you need to find literature linked to your main research questions and problem. Respectively, if you are writing it as a stand-alone task, you'll have to pick a relevant topic and central question upon which you'll be collecting the literature. Earlier in the day in this guide we suggested some engaging topics to guide your search.

Step 2: Conducting Research

When you yourself have a obviously defined topic, it is time to start collecting literature for your review. We recommend starting by compiling a summary of relevant key words related to your central question—to make the complete research process much simpler and help you find relevant publications faster.

When you yourself have a list of key words, use them to find valid and relevant sources. At this point, make sure to use only trusted sources, such as for example ones from university libraries, online scientific databases, and so on

After you have found some sources, make sure you define if they are actually strongly related your topic and research question. To truly save you time, you can read abstracts to have general a few ideas of what the papers are about, instead of the whole thing.

Pro Tip: Once you finally look for a few valid publications, have a look at their bibliographies to discover other relevant sources as well.

Step 3: Assess and Prioritize Sources

Through your research, you will probably find lots of relevant literature to include in your literature review. At this point, many students make the error of wanting to fit their collected sources into their reviews. We suggest looking at what you’ve collected once more, assess the available sources, and select the absolute most relevant ones. You most likely won’t be able to read everything you find on certain topic after which be able to synthesize all of the sources into a single literature review. That’s why prioritizing them is important.

To judge which sources are worth including in your review, keep in mind the next criteria:

  • Credibility;
  • Influence;
  • Novelty;
  • Innovation;
  • Key insights;
  • Relevancy.

Moreover, as you read the sources, don’t forget to make notes on whatever you can incorporate into the review later. And start to become sure to truly get your citations in position early on. In the event that you cite the selected sources at the first stage, you'll find it more straightforward to create your annotated bibliography later on.

Step 4: Identify Relationships, Key Ideas, and Gaps

One which just move on to outlining and writing your literature review, the final step is determining the relationships between the studies that already exist. Distinguishing the relationships will help you organize the existing knowledge, build a solid literature outline, and (if necessary) indicate your own research contribution to a specific field.

Some of the key points to keep an eye out for are:

  • Main themes;
  • Contradictions and debates;
  • Influential studies or theories;
  • Trends and patterns;
  • Gaps.

Here are some examples: Common trends can include a give attention to specific categories of people across different studies. There may be increased interest among most researchers in certain facets of the topic when it comes to key themes. Contradictions can sometimes include some disagreement concerning the theories and outcomes of research. And finally, gaps most often reference a lack of research on certain aspects of an interest.

Step 5: Make an Outline

Even though students have a tendency to neglect this stage, outlining is one of the most significant steps on paper every academic paper. This is actually the easiest way to arrange the body of one's text and ensure that you haven’t missed any such thing important. Besides, having a rough idea about what you are likely to write about in the paper will help you obtain it right faster and easier.

Earlier in the day in this guide, we already discussed the basic structure of a literature review and gave you a typical example of a good outline. During this period of the workflow, you need to use all of the knowledge you’ve gained from us to build your own personal outline.

Step 6: Move on to Writing

Having found and created your entire sources, notes, citations, and a detailed outline, you can finally get to the writing the main process. During this period, all you need to complete is follow the plan you’ve created and keep in mind the general structure and format defined in your professor’s directions.

Step 7: Adding the Final Touches

Most students make a common mistake and miss out the final stage of the method, which includes proofreading and editing. We recommend taking the full time for these steps to ensure your work is likely to be worth the greatest score. Don't underestimate the value of proofreading and editing, and allocate enough time for these steps.

Pro Tip: Before moving on to proofreading and editing, make sure to set your literature review aside for a day or two. This will offer you a chance to just take your mind from it and be able to get back again to proofreading with a fresh perspective. This tip will make sure that you won’t lose out on any gaps or errors that might be within your text.

These steps can help you create a top-notch literature review with ease! Need to get more suggestions about how to handle this body of work? Listed below are the top 3 tips you will need to keep in mind when writing a literature review:

  1. Good Sources
    When working on a literature review, the most important thing any writer should keep in mind is always to find the best possible sources due to their MOP. Which means while doing initial research, you should select and filter through about 5-10 different choices. The stronger a piece of literature showcases the central point, the better the caliber of the entire review will be.
  2. Synthesize The Literature
    Ensure that you structure the review in the most effective way possible, whether it be chronologically, thematically, or methodologically. Determine what it is you may like to say exactly, and structure the source comparison accordingly.
  3. Avoid Generalizations
    Keep in mind that each bit of literature will approach the MOP from the different angle. As the author, make sure to present the contrasts in approaches clearly and don’t include general statements that offer no value.
