#What does literature review mean: definition, function and whether it counts as a paper
Key points of this article
- A literature review is a review and review of existing research on a certain issue, with the core being synthesis, comparison and evaluation.
- It is not a list of literature, nor a summary of each article. It is not a review without summary and evaluation.
- Reviews usually do not provide new empirical data, while research papers mainly focus on original research, and the two cannot be confused.
- Before writing the review, first set up a classification framework according to the theme, and then put each document into the corresponding position.
- You can use bilingual comparison when reading English literature, but important points should be checked back to the original text.
When many students see "submit a literature review" in their instructor or course syllabus for the first time, they will stop first: What on earth is this? Should I write an essay or just make a list of articles I have read? Most of the people who search for "What does a literature review mean?" and "Is a literature review a paper?" are at this stage. They have tasks at hand but do not yet have a clear concept.
This article only answers conceptual questions: what is the definition of a literature review, what role does it play in academic work, and what is the difference between it and research papers and reading notes. After reading, you will be able to judge which category the task at hand belongs to, and also know where to start next.
Next, I will give a conclusion first, then break down the concepts, and finally talk about a practical approach to reading and organizing literature.
What does literature review mean? One sentence conclusion
A literature review is an article that collects published research on a certain topic, summarizes, compares, and evaluates it according to certain clues, and clearly states "what is currently known in this field, what are the debates, and what are the gaps." Its core is synthesis and review, rather than a piece-by-piece retelling.
| your situation | Recommended practices | reason |
|---|---|---|
| The course assignment required a "literature review" and did not specify the word count. | First ask about the number of pages and documents, and then organize them into sections by topic. | Different schools and instructors have very different length and format requirements. |
| Want to learn about a new field but don’t know the research context | First read review articles in recent years, and then review classic research | The existing reviews themselves are sorted out maps. |
| You should write "research status" or "related work" for your paper | Group according to viewpoints or methods, and write down the relationships and shortcomings between each group | This section provides a rationale for your research question |
| I just finished reading a paper and wanted to take note of the key points. | Write reading notes to record the purpose, methods, conclusions and personal thoughts | Reading notes are for a single document and do not require cross-document synthesis. |
| There are already many documents and I don’t know where to start. | First list the keywords and classification framework, and then put the documents into the framework | The framework determines the structure, which is clearer than listing it in chronological order. |
The definition of literature review: three things: synthesis, comparison, and review
what is it
A literature review contains at least three actions. The first is synthesis, which combines research scattered in different journals and different years under the same issue. The second is comparison, which explains the similarities and differences between different studies in terms of research objects, methods, samples and conclusions. The third is commentary, which points out which conclusions are reliable, which evidence is insufficient, and which questions no one has answered so far.
Without any action, the article can easily become something else. Only a synthesis without review is close to a "bibliography"; a review without synthesis is more like a book review of a single paper.
What role does it play in academic work?
A literature review has four main functions.
- confirm whether the question has been answered : avoid repeating the same question. - give readers a map : let new readers quickly understand the main ideas and representative studies in the field. - provide the basis for research and design : what variables to choose, what methods to use, and which validated scales to refer to are often based on reviews. - training critical reading skills : the process of writing a review is the process of learning to judge the evidence of an article.
A common misunderstanding is to write a literature review as a "summary by article": what is said in the first article, what is said in the second article, and finally a list of references. This way of writing has information, but it is not comprehensive, and the reader cannot see the relationship between the studies.
Another misconception is that "the more citations, the more like a review." The review needs to select criteria, such as time range, research type and topic boundary. There are no selection criteria, no matter how many documents are piled up is just a list.
# Core comparison
| Contrast item | Journals reviewed | Research papers | Reading notes |
|---|---|---|---|
| Main object | A number of published studies | The author's own research data or theoretical deduction | It's usually a single document. |
| Core task | Research on carding, comparison and evaluation | Raise and test new questions or hypotheses | Record and digest the contents of an article |
| Whether to provide new empirical results | Usually not. | Generally have (new results of an experiment, investigation, or theory) | No |
| Typical structure | Break down by topic or time, and finally write the research blank. | Introduction, method, result, discussion | Literature information, main points, personal evaluation |
# is literature review a paper?
Strictly speaking, literature review is a type of academic articles, which belongs to papers in a broad sense. The review paper (review article) published in the journal is the academic achievement published independently. However, in course assignments or dissertations, literature review is often an assignment or a chapter in a thesis.
The criteria can be tested by a question: does the main conclusion of the article come from the new data collected or analyzed by the author himself? If not, it is only a summary and evaluation of the existing research, then it belongs to the review; if so, it is closer to the research paper. Before writing, readers are advised to ask the tutor or course to confirm whether this is an independent review assignment, part of the paper, or whether it needs to include new analysis.
# how to use it in practice: use OmniDoc to read documents and organize manuscripts
The difficulty of literature review is often in the early stage of reading. If you have an English PDF in your hand, the following steps can help you string together your reading and organization.
- do bilingual control when reading the literature : upload PDF on omnidoc.top (scan version is also available), select bilingual control or translation only, and read key paragraphs against the original text after downloading the results.
- only three things are recorded in each document : research problems, research methods, and main conclusions, each written in a note in one sentence for later horizontal comparison.
- frame by topic *: group notes by point of view or method and draw a simple framework, such as "dispute over definition", "research method" and "divergence of conclusions".
- write the first draft in Word : divide chapters according to the title style, write a summary, then a review, and finally put in a quote. You can also use the UniDoc Web Page Editor (app.unidoc.top) when you need to collaborate online or transfer to and from Word files.
- check translation and citation : machine translation may mistranslate technical terms. The quoted point of view should be confirmed back to the original text, and the page number and year should be checked one by one.
Suppose you want to read a 30-page English paper, first look at the abstract and conclusion to determine its relationship to the topic, and then use the bilingual contrast intensive reading method, which usually takes less time than reading through the full text, and it is easier to extract the main points that can be compared.
# which method is suitable for you?
- if you are new to a field : first look for review articles in recent years to make an overall impression, and then review the original research according to the reviewed references. - if you are going to write a course assignment : confirm the length and format first, organize the literature in a classification framework, and do not seek to cover all the research. - if you are going to write a research status for a paper *: focus on differences between opinions and unresolved problems, and let it naturally lead to your research questions.
# frequently asked questions (FAQ)
1. Is literature review the same thing as literature review?
It is usually a different way of saying the same concept, and literature review is common in English. The specific requirements of the course or journal shall prevail, and the writing can be unified.
2. How many articles should be read in literature review?
There is no fixed number, depending on the scope and length of the topic. The key is to cover the core research and the progress made in recent years, and to describe the screening criteria, such as time range and literature type.
3. Can we use general chat robots to generate literature reviews directly?
It can help you sort out your ideas or outline, but it may make up literature that does not exist, or it may misgeneralize your point of view. Citations and conclusions must be checked item by item back to the original text.
4. Must the literature review come to a conclusion?
Generally, a summary is needed to summarize the main consensus, differences and gaps in the existing research, and to indicate where the follow-up research can be carried out.
# Summary
Literature review is a synthesis and review of the existing research on a certain problem, which aims to clarify the current situation and research gaps in the field. It usually does not provide new data, so it is different from papers based on original research and reading notes for a single document. After figuring out these differences, set up the framework according to the topic, read carefully and check the original text one by one, and you will have a clear direction for writing.
