It takes about three months to write a literature review.

Because I have just entered the first year of graduate students and haven't chosen a topic yet, I can read a lot of reference materials according to my research direction at this time to understand the industry trends and the latest research results. So you need to read at least 100 references to get a preliminary understanding of industry trends. After reading the references, a summary can be completed in about 3 months.

I. Definition and function of reference

Reference refers to the relevant literature information resources cited for writing or editing papers and works, which are generally placed at the end of graduation thesis. References are necessary marks made by authors to explain problems, cite arguments and directly or indirectly cite other people's research results, which are used to show the owner and source of the cited content and can protect the intellectual property rights of the authors. A complete reference is an indispensable part of the paper research. Together with the paper, it constitutes a complete expression of the rigorous scientific research process, indicating the reference materials that students have read, providing relevant materials for specific topics, and facilitating readers to read.

Secondly, the classification of references.

According to different types, it can be divided into:

1. Monographs, papers and reports.

2. Journal articles.

3. Precipitated documents in the paper set.

4. newspaper articles.

5. Electronic literature.

6. thesis.

Third, the reference format

Different types of references have different citation formats and different citation marks, as follows:

For monographs [M], conference proceedings [C], newspaper articles [N], journal articles [J], dissertations [D], papers [A] and precipitation documents in magazines [G].
