Yes, this is the basic requirement of the paper format.

Cross-reference is to use the reference number to insert the text as an index, and it needs to be an endnote.

Therefore, cross-references and endnotes do not conflict, and no matter how you toss, you insert documents with the built-in functions of Word. Compared with using document software, the advantage of Word's built-in function is that it can jump (some software supports it and some don't), but the disadvantage is that it is more troublesome. At the same time, the bibliography has to be written/generated by itself. Moreover, the index generated in this way is based on the bibliographic order, which should actually be the other way around, that is, the index order determines the bibliographic number.

What's more, if you copy and paste the bibliography directly from the internet without using document management software, the quality of the bibliography will never be too high.

Do the references in papers have to be cross-referenced?

It's not necessary.

First, put the document to be cited in the place where it is cited. Then, the cited literature, right click and item number are given. Find the place to quote in the text, put the cursor there, and then click Enter: Quote. Found: Cross-reference, click enter. Open a box.

Set the box and select the hyperlink. Please be sure to choose it. After selecting the literature to be cited, insert it like this, and you can set the small label as superscript.

First, insert the text that needs to be quoted into a blank page, put the cursor in front of the text, and then click the "Numbers" button in the shortcut bar. There are many formats to choose from, and you can also customize the numbering format, and refer to the numbering.

Do I need to cross-reference after the reference is converted into plain text format?

Yes, I know. Generally, when writing a literature review or paper, references are always quoted in the article. In the process of writing a paper, we often add or delete references to a certain extent, which makes the reference numbers quoted in the paper inconsistent with those added or deleted. If you modify it by hand and deal with it one by one, the workload is heavy, and you are often confused and don't know which one is which. Then, use the Cross Reference function.
