The main purpose of setting up the directory is:
1, let readers have a general understanding of the content and structure of the full text before reading this article, so that readers can decide whether to read it, whether to read it intensively or skim it.
2. It is convenient for readers to choose a sub-argument in the text. A long paper has many sub-arguments besides the central argument. When readers need to know more about a sub-argument, they can rely on the table of contents to save time.
The table of contents is usually placed in front of the text of the paper, so it is the guide map of the paper. To make the directory really play the role of a guide map, we must pay attention to:
1, accurate. The content must be consistent with the outline of the full text. In other words, the title, subtitle and content of this paper are one-to-one correspondence.
2, clear and correct. The table of contents should be marked with the page number of the table of contents one by one in the text. Page numbers must be clear and correct.
3. complete. Because the table of contents is the guide map of the paper, it must be complete. In other words, all the contents of the article should be reflected in the catalogue and must not be omitted.
There are two basic types of directories:
1, a directory in words.
2. Digital catalogue. This kind of catalogue is rare. However, it is easy for readers to read long speeches, and some of them use this method. ;
