It is a scientific document.
Format and writing
The format of literature review is different from that of general research papers. This is because research papers focus on research methods and results, especially positive results, while literature review requires readers to introduce detailed information, trends, progress, prospects and comments in the above aspects. Therefore, the format of literature review is relatively diverse, but generally speaking, it includes the following four parts: preface, theme, summary and references. When writing a literature review, you can write an outline according to these four parts, and then write according to the outline.
The preface mainly explains the purpose of writing, introduces related concepts and definitions, outlines the scope, and briefly explains the current situation or focus of debate of related topics, so that readers can have a preliminary outline of the problems to be described in the full text.
The theme part is the main body of the summary, and the writing methods are diverse and there is no fixed format. It can be summarized in chronological order and compared from different angles according to different problems. No matter which format is adopted, the collected documents should be summarized, sorted, analyzed and compared, and the historical background, present situation and development direction of related topics and comments on these issues should be made clear. In the theme part, we should pay special attention to representative, scientific and creative references and comments.
The summary part is somewhat similar to the summary of the research paper. It briefly summarizes the theme of the full text, and authors who have studied the summarized theme had better put forward their own opinions.
Although references are placed at the end of the article, they are an important part of literature review. Because it not only shows the respect for the author of the cited literature and the basis of the cited literature, but also provides clues for readers to discuss related issues in depth. So take it seriously. The arrangement of references should be clear, easy to find and accurate. Regarding the use of references, the recorded items and formats are the same as those of research papers, and they are not repeated.
