References should be left aligned. But if the document is too long, the newly opened second sentence needs to be indented by two spaces, so as to distinguish different documents and understand them together. No confusion.

How to align the up and down lines in a reference?

References are a very important part of academic papers, which can show the author's in-depth research and understanding of related documents. In the process of writing, how to correctly check the up and down lines of references is a detail that needs attention.

In order to realize the reverse production of the upper and lower lines in the reference, the following methods can be adopted.

1. In Word, open the paragraph window, select the multi-line option, and set the alignment to be justified.

2. Add a blank line between references, which can make the distance between references more obvious and make alignment easier.

3. If the reference item is more than one line, the second line and the following contents need to be indented by half a character to show the difference.

4. If the reference entry contains URL or DOI 1, it can be placed after a line, enclosed in square brackets, and wrapped after the square brackets to avoid the URL or DOI destroying the reference effect.

In a word, it is an important academic writing skill to correctly align the up and down lines of references, which needs the author's attention. By adopting the above methods, we can easily compare the references between the upper and lower lines, thus making our academic papers more standardized and tidy.
