Writing papers and revising references are very troublesome. If you delete one and add another, you need to change a long list of numbers. What should we do? I recommend a simple method: the endnote method is as follows (taking Word2003 as an example): 1. Move the cursor to the place where you want to insert the reference, and select Insert-Citation-Footnote and Endnote from the menu. 2. Select "endnote" in the dialog box, select "automatic numbering" as the numbering method, and suggest "section ending" as the location. 3. If AutoNumber is not Arabic numerals, select Options in the lower right corner and select Arabic numerals in the numbering format. 4. After confirmation, insert a superscript "1" here, and the cursor will automatically jump to the end of the article, which is preceded by a superscript "1", which is where the first reference is entered. 5. Change the format of the superscript "1" at the end of the article to normal (remember to change the format, don't delete it and re-enter, otherwise the reference will move in the future, and the serial number will remain unchanged), and then enter the reference inserted at the back (the format is slowly entered according to the requirements of the magazine, as if there is no way to simplify it). 6. Double-click "1" in front of the reference, and the cursor will return to the place where the reference was inserted in the article content, and you can continue to write the article. 7. Insert an endnote in the next place where you want to insert a reference according to the above method again, and a "2" will appear (Word has automatically sorted it for you), and continue to enter the reference to be inserted. 8. After quoting all the references, you will find that there is a short horizontal line in front of the first reference (which can only be seen in page view). If a spread is referenced, there will also be a long horizontal line in the spread. You cannot select or delete these rows. This is the sign of endnotes, but the format of general scientific papers cannot have such lines and must be deleted. 9. Switch to normal view and select View-Footnote from the menu. At this point, the edit field of the endnote appears at the bottom. 10. Select "Endnote Delimiter" from the drop-down menu on the right side of the endnote, and a short horizontal line will appear. Select and delete it. 1 1. Select Endnote Continuation Delimiter from the drop-down menu. This is a long horizontal line. Select and delete it. 12. Switch back to page view, and reference insertion has been completed. At this time, no matter how the article is changed, the references will be automatically arranged in order. If it is deleted, the following references will disappear automatically and there will be no errors. 13. The more references, the greater the advantage of this method. It's not over yet. How to put square brackets around the label? It's simple: throughout the text, look for the endnote mark E and replace it with [&; ] yes; If footnotes are used, find the footnote mark f and replace it all with [&; ] (Note that the "Unlimited Format" button is grayed out when searching). Although there are many steps, just operate once and you will know that it is very simple.
