Mark the cited documents: place the cursor where the documents need to be inserted, select "Citation" on the menu bar, and insert endnotes. By default, Roman endnotes will appear at the end of the document or at the end of the current chapter. Click the arrow on the right side of the footnote menu to enter the footnote setting menu, just select Arabic numerals as the format number.

There are many ways to mark cited documents.

The main method is: select the paragraph to be quoted, click the quotation option on the word panel, and then click Insert Endnote. The default comment is "I", which can be changed to digital form.

Click the drop-down option of footnote in the reference option, and the setting menu of footnote and endnote will appear. Select the numbering form in the numbering format, and then click Apply.

Finally, the annotation format of the reference should be displayed, and then the source should be entered after the number. Click the footnote/endnote separator to cancel the separator.
