What are the methods of literature search, and what are the main methods of literature search

Literature search method:

1. Direct method: also known as common method, refers to the method of directly using the retrieval system (tool) to retrieve literature information. It is further divided into the forward inspection method, the reverse inspection method and the spot check method.

2. Follow-up method: Follow-up method refers to the method of using the retrieval system to retrieve literature information from far and near in chronological order. This method can collect systematic literature on a topic, and it is suitable for literature retrieval on larger topics.

For example, if you know the beginning age of a topic and need to understand the whole process of its development, you can use the forward search method to start from the original date.

3. Back-checking method: The back-checking method is a method of using retrieval tools to conduct literature retrieval from near to far, from new to old, in reverse chronological order. This method is the fastest way to get the most up-to-date information.

4. Spot check method: Spot check method refers to the method of selecting the time period when the literature information about the project is most likely or appearing the most, and using the search tool to carry out key searches according to the characteristics of the project.

5. Retrospective method: It refers to the method of tracing the original text (cited literature) one by one without using the general retrieval system, but using the references listed at the back of the literature, and then expanding the scope of literature information from the reference list listed after the original text, and tracing it one by one. It can snowball and obtain better search results based on the citation relationship between documents.

6. Round-robin method: also known as segmentation method or comprehensive method. It is a direct method and retrospective method alternately used in staging, in order to learn from each other's strengths and cooperate with each other to obtain better search results.

Literature search methods include the following:

1. Author's approach.

Many search systems have an author index, an institution (institutional author or the author's institution) index, and a patent literature search system has a patentee index, and the way to search from the name of the author, editor, translator, patentee or the name of an institution or organization is collectively referred to as the author's route.

2. The title includes the title of the book, the title of the journal, the title of the article, etc.

Some search systems provide a search by title, such as a bibliography of titles and a bibliography of journals.

3. Classification approach.

Literature is searched by subject classification system. This approach is based on the knowledge system as the center of classification and arrangement, therefore, it can reflect the systematization of the discipline, reflect the subordination, derivation and parallel relationship between the discipline and things, and facilitate us to search for literature from the scope of the discipline, and can play a role"Touch bypass"role. Literature is retrieved from the classification route, mainly using classification catalogues and classification indexes.

Fourth, the thematic approach.

Literature is searched by subject headings that reflect the content of the literature. Because the topic method can reflect all aspects of the literature of a topic, it is convenient for readers to conduct a comprehensive and systematic thematic study of a certain issue, a certain thing and an object. Through subject catalogs or indexes, we can find various literature sources on the same topic.

5. Citations.

The references or citations attached to the document are one of the external characteristics of the document. The indexing system that uses this kind of citation is called the citation indexing system, which provides a way to retrieve citations from the cited **, which is called the citation pathway.

The role of literature search.

There are only a few roles of literature search in educational research:

1. It can provide the basis for topic selection.

In the process of determining the topic, it is necessary to have a good understanding of the existing research. What are the results of previous research? How did they do it?

What is the focus of the study? Methodology? What issues have been resolved or largely resolved?

What issues remain unresolved? What needs to be further amended or added? What are the main differences on this issue at home and abroad?

The focus is on**? How many representative pieces are there? Who are the representatives?

For topics that have not been set foot in before, it is necessary to understand the research value of the topic from the side through the review of relevant literature. Where to start? What methods and means can be used?

Can similar disciplines or topics be used for reference? All this, on the basis of the absence of possession of literature, is inconceivable.

2. It can expand the field of vision.

Marx once likened the use of literature to standing on the shoulders of giants. Full possession of literature can broaden researchers' thinking, deepen their understanding of problems, and inspire deeper thinking. Frequent reference to the literature can stand at the forefront of the research field, track the latest research results and methods at home and abroad, and get inspiration from them, find possible answers to solve problems, and make the research topics stand at a higher starting point.

3. Unnecessary repetition can be avoided.

One of the basic purposes of literature retrieval is to avoid duplication of work, to avoid repeating problems that others have solved, to avoid repeating mistakes that others have made, to avoid detours, and to improve research efficiency.

The role of literature retrieval in the whole research is even important, and the value of research results is related to the quantity and quality of the literature in possession. Conducting research in the absence of literature and intelligence information is often either blind or repetitive at a lower level, which is a waste of people and resources.

I don't know if the above has solved your doubts.
