How to set up reference cross-references in Word so that the superscript numbers are not messy

Key points of this article

When the reference list is automatically numbered, use "Numbered Item" for cross-referencing. When manually entering the number, bookmark the numbered text and then use "Bookmarked Text" for citation.
The text number is made into a field. After the order of documents is adjusted or added or deleted, select all documents and press F9 to update them synchronously. There is no need to manually change them one by one.
The superscript should be set on the field results. If it is lost after updating, check the format switch of the field code, fill it in and reset it.
When checking, randomly click on the text number to see if it jumps to the corresponding document, and confirm that the number increases in the order of first appearance.

When many people write papers, the reference numbers in the text are typed manually [1], [2]. When adjusting the order of a document, all subsequent numbers must be changed. If one is missed, it will not be correct. Using the cross-reference function of Word, you can make the numbers in the text point to specific entries in the reference list at the end of the text. You only need to update them once and the numbers will be synchronized.

This article is written for readers who are writing papers, graduation projects or submitting manuscripts and need to deal with reference numbers. The following will talk about two methods, and explain how to keep the numbers superscripted and not lose the format after updating. Finally, the verification method after completion will be given.

How to do reference cross-referencing? One sentence conclusion

The core idea is: mark the reference entries first, and then quote this mark in the text. Use "Number Item" when the list is automatically numbered, and "Bookmark" when the list number is entered manually.

your situation	Recommended practices	reason
Reference lists are automatically numbered in Word	Cross-referencing with numbered items	Directly quote the number of the paragraph in the list without adding additional bookmarks
Numbers are entered manually [1], [2]	Bookmark numbered text and cite it using bookmarked text	There is no optional automatic numbering option for manual numbering. The bookmark can point to this text.
The journal requires superscripts, no square brackets	Remove the square brackets for the list number, and enter the text brackets separately.	Cross-referencing will bring out the original numbering format of the list
Citing multiple documents at the same location	Insert a quote for each article, manually enter a comma or dash in the middle	Each reference corresponds to a domain, and it is more reliable to update it individually.
Documents will be added and deleted during writing	All numbers are made into fields. After the changes are completed, choose to update them all.	The number will automatically change with the list, no need to modify it one by one.

Before you start: Confirm these points first

The numbering format of the target journal or school. Numbering in square brackets is common in China, and some journals require superscript numbers. The two writing methods have different formatting requirements, so confirm them first before starting to avoid rework.
Whether the reference list is automatically numbered or typed by hand. This determines whether to use numbered items or bookmarks. You can click on the first item in the list to see if the number is automatically generated with gray shading, or directly check whether the number can be adjusted in the list format.
Numbering order. Most formats require numbering in order of first occurrence. Decide on the order of documents first, and then create citations. Later adjustments will save you a lot of trouble.
Whether the field code needs to be displayed. After the cross-reference is inserted, it is displayed as a field, which usually looks like ordinary text. Allow time for inspection and switch display codes if necessary.
Save a copy. Before making large-scale modifications to references, save a separate file so that you can roll back if something goes wrong.

Steps to cross-reference references in Word

Open the document and confirm that the reference list is at the end of the article. Each reference is a separate paragraph. Do not combine multiple references into one paragraph.
Determine the list type. If it is automatic numbering, go directly to step 4. If the number is entered manually, select the number in front of the first document (without square brackets), find the bookmark function in the insert menu, and name it starting with a letter without spaces, such as ref_wang2021. Repeat this for each document.
Place the cursor at the location where the number needs to be displayed in the text, and open the Word cross-reference dialog box.
Select the reference type according to the situation: select "Numbered Item" for an automatically numbered list, and select "Bookmark" for a manually numbered list.
Select the document you want to cite in the list. In the citation content item, select the paragraph number for the automatically numbered list, select the bookmark text for the manually numbered list, and check the option to insert a hyperlink to make it easier to click to jump later.
After inserting, select this number result and set it as superscript. A common shortcut key is Ctrl+Shift+=. If your format requires square brackets, enter them manually outside the field to avoid them being superscripted or overwritten by updates.
Repeat steps 3 through 6 to insert a cross-reference for each reference location. When quoting multiple articles at the same position, manually enter commas in the middle after inserting them separately.
Select all documents (Ctrl+A), press F9 to update all fields, and then check whether the number corresponds to the document one by one.

Check each item after completion

After the update is completed, it is recommended to check each item according to the table below.

Check items	How to see it	What should you do if there's a problem?
Does the number point to the correct document?	Randomly hold Ctrl and click several body numbers to see if it jumps to the corresponding entry	Check the entries selected during reference, reinsert or update the domain
Numbering sequence	Read through the text from the beginning to see if the first appearance of the number increases in number	After adjusting the order of the documents, select all and update according to F9
Check if the superscript is complete	Check each number one by one to see if the superscript is the superscript and if anything is missed	Select the missing domain, reset the superscript, and update the check again
Whether the domain is displayed as a code	If you see a character starting with a REF, it means the domain code is displaying	Press Alt+F9 to switch back to the result display; if it shows as a number, it is normal
After the additions and deletions of the literature	Check if you see a prompt like "No citation found."	Usually, the bookmark is deleted, and after re-adding the bookmark, the domain is updated
Whether it meets the submission requirements	Check the writing of square brackets, superscripts, and commas against the submission instructions	Adjust the style of list numbering or the position of body parentheses

One more reminder: cross-referencing only ensures that the numbers and lists correspond; they cannot judge whether the literature information is complete or the citation content is accurate. Important citations should still be cross-checked against the original text.

📊 Core Comparison: Numbered Items and Bookmarks

The main difference between the two approaches lies in what they rely on. The specific differences are as follows.

Comparison items	Numbered items	Bookmark
What do you rely on?	Automatic numbering of lists	The text you manually marked
After the additions and deletions of the literature were made	Automatic renumbering	New literature must be bookmarked first; otherwise, it cannot be cited
A suitable list	All numbering is generated by Word	Manually enter the number

If the list is already automatically numbered, prioritize numbered items and do not need to bookmark them separately. If the list is hand-typed, bookmarks are a safer choice.

❓ Frequently Asked Questions (FAQ)

1. What should I do if the superscript disappears after updating the domain?

First, check whether the end of the domain code contains a toggle for the reserved format. If not, you can add it in the domain code and then reset the superscript. After the update, check again to confirm the format is intact.

2. Can manually typed numbers be used as serial items?

Generally not. Numbered items only recognize list numbers automatically generated by Word. Manually entered numbers should be referenced using bookmarks plus "bookmark text."

3. After pressing F9, it shows "No source found"—what does this mean?

Usually, the corresponding bookmark has been deleted or renamed. Find this citation, check if the target document still has bookmarks, re-add it, then select all to update.

4. If one location cites multiple literature, can only one cross-reference be inserted?

The usual approach is to insert a cross-reference per document, with a comma or short line manually entered in between. This makes it more convenient to update and inspect separately.

📝 Summary

Make reference numbers cross-reference; after changing the order of references, simply select all and update them with F9, keeping both numbers and superscripts consistent. First, confirm the list type, then select the numbered item or bookmark, and finally check according to the checklist. Once you master this method, the reference numbers in your thesis won't get mixed up.
