How to set the reference numbering format [1-3]

Explain how to set [1-3], [1], and superscript numbers in the text and keep them consistent in Word, including numbering in order of appearance, automatic updating of fields, merging intervals, and batch changing to superscripts, and provide a checklist.

Key points of this article

  • The citation number in the text and the reference list at the end of the article are two different things. Decide on the citation format first, and then discuss the layout of the items.
  • Numbers should be arranged in the order of first appearance. Consecutive references are combined into [1-3], and discontinuous references are written into [1,3,5].
  • Use captions and cross-references to generate numbers. After adding or deleting documents, you only need to update the fields instead of manually changing them one by one.
  • Superscript is a character format, which can be set uniformly like square brackets. When replacing in batches, be careful to only change the reference part.
  • Before submitting the manuscript, check whether the numbers are continuous, whether the intervals are merged, and whether the superscripts are consistent. The format shall be subject to the regulations of the target journal or school.

When writing a paper, the citation marks in the text look simple, but in fact, they are easy to make mistakes: the first cited literature is listed at the back, and then all the numbers are misplaced, or [1-3] is written as [1-1-3], and there are a few omissions when changing it to superscript. This kind of problem is different from the typesetting of reference entries at the end of the text, it belongs to the problem of numbering scheme and character format.

This article is written for readers who need to complete graduation thesis, course report or submit manuscript in Word. After reading, you will know how to generate reference numbers according to rules, how to unify [1-3] with superscript form, and how to quickly check after modification. The operations in this article are based on the common functions of Word and do not depend on the menu position of a certain version.

Should the reference number be [1-3] or superscript? One sentence conclusion

First set the format according to the requirements of the school or journal, and then set it uniformly in Word; if there are no rigid requirements, just choose one and keep it consistent throughout the text. The way numbers are generated (in order of appearance, automatically updated by domain) affects the workload of later modifications more than the appearance.

Before you start: Confirm these points first

First, confirm the format requirements. Different schools and journals have different requirements for square brackets, superscripts, and whether to merge intervals. Some require [1–3], some require [1,2,3]. Check it out first, all subsequent settings will revolve around it.

Second, confirm the numbering sequence. Most specifications require numbering in the order of first occurrence in the text. If you write Section 5 first and then Section 2, the reference numbers should be based on the order in which the references appear in the main text, not the order in which you add the references.

Third, distinguish between citation marks and reference entries. [1] in the main text is a citation mark, and the entry at the end of the text is a reference list. The two numbers need to correspond one to one. If the list was copied from a PDF or other software, it may have original numbering formatting that needs to be cleaned up separately.

Fourth, decide whether to use a domain. Fields are automatically generated content in Word that can be updated. Put the citation number in the title or cross-reference. After adding or deleting a document, you only need to update it to renumber it. This is especially important for papers with dozens of citations, which are easy to miss when editing by hand.

Fifth, back up the original. Batch replacement format will change many places at once. Save a copy first so you can roll back if something goes wrong.

Steps to set [1-3] numbering in Word

  1. Organize the order of documents. Read the entire text in the draft first, number each document in the order of first appearance, and make a comparison table.
  2. Add numbers to reference entries. In the reference list at the end of the article, give each document a definite serial number to make it consistent with the comparison table. This step is the basis for subsequent references.
  3. Insert reference number. Insert numbers using captions or cross-references at locations in the text that need to be cited, rather than entering numbers directly. This way the number will be associated with the list entry.
  4. Handle continuous references. When citing several consecutive documents, it is written as [1-3]; if there is a missing document in the middle, it is written as [1,3,5]. Note that only consecutive numbers are combined into intervals. Just choose one of [2,3] and [2-3] as specified.
  5. Unify bracket or superscript styles. If superscript is required, first use the search function to locate all reference marks in the full text, and then set them as superscripts. Be careful to select only the quoted part, and do not select the surrounding punctuation and text.
  6. Limit the range when replacing formats in batches. If the original text has been written as [1], [2] and the like, you can use the find and replace function to use wildcards to match the numbers in square brackets. When replacing, only set superscripts for the replacement content. Try it on a small area before replacing.
  7. Update all domains and directories. After the modification is completed, select all documents and update the fields, and confirm that the text number and reference list are refreshed simultaneously.

# check item by item after completion

Check itemWhat do you think?What if there's a problem?
Whether the numbers are sorted by first occurrenceRead the text from the beginning and write down the position where each number appears for the first timeUpdate fields after adjusting the order of references, and then check them one by one
Whether the text corresponds to the list one by oneRandomly select 5 citations and go back to the list to check the literature.Find out the misplaced entries, correct the comparison table and reinsert it.
Whether the interval writing method is unifiedSearch for "-" and "," to see if consecutive references are merged as required.Replace uniformly according to the regulations, and be careful not to mistakenly change the symbols in the title and data.
Is the superscript consistent in the full text?Use the find function to search for square brackets and confirm the character format one by oneAdd superscripts to missing references, or uniformly change back to square brackets
Is there a residual old number?Search for "[" to see if there are unrelated fields of handwritten numbersChange handwritten notes or cross-references to avoid subsequent mislocations.
Whether to synchronize after deleting or adding new documentsDelete a document and try to see if the number is adjusted automatically.If it is not adjusted, check whether the reference is actually associated through the domain

If the document is from a PDF, such as a journal template or a scanned copy downloaded from the Internet, the text may not be edited directly. You can first use the PDF editing function or OCR function of the OmniDoc desktop client to identify the text, and then export it to Word for modification. The exported format still needs to be checked one by one.

# frequently asked questions (FAQ)

1. Which is right, Ref. [1-3] or [1-1-2-3]?

Both are common, and the difference lies in whether consecutive references are merged. Most specifications require consecutive numbers to be written as intervals, such as [1-3], and discontiguous ones separated by commas. The specific provisions of the school or periodicals shall prevail.

2. Is it okay to use full-angle brackets in reference [1]?

If square brackets are required, half-angle square brackets [] should be used. Full-angle brackets [] are not suitable in most paper specifications. It is suggested that the full text should be unified and should not be mixed with English and Chinese.

3. After the reference number is changed to superscript, can it still be updated with the domain?

Sure. The superscript is in character format and does not conflict with the field. Note, however, that the original format may be restored after updating the field, so it is recommended to update the number first and then set the superscript uniformly.

4. Why didn't the serial number change after deleting a document?

It is usually because the reference is not generated through a caption or cross-reference, but is manually entered. Replace these handwritten numbers with domain references, and then update the full text.

5. Do you need to check the number generated by the machine?

Need. Whether the number is generated by hand or with the help of a tool, it should be checked item by item against the literature list. Important information should also be checked manually when it comes to machine translation or text recognition.

# Summary

The key to the numbering format of reference [1-3] is to first determine the rules, then use the domain to generate the number, and finally unify the superscript or square brackets. Set up in this order, adding and deleting documents and modifying the full text can be consistent. If you check the list item by item before handing in the manuscript, you can reduce rework.
