I’m writing a paper with around 100 citations, which are listed in the end. Often, a particular source will be cited more than once, at different places in the paper. I could make the endnote at the first reference, and then make a superscript copy at the next reference. But then if I add more references prior to that reference, they will not match.
It served me extremely well in writing papers, keeping track of hundreds of citations, and formating them all automatically as I was writing and modifying my papers.
There are two functions under the “Insert” Menu that I use for this situation: Footnote and Cross-Reference.
First, click on “Footnote” - that gives you the option of footnotes or endnotes. Click on endnotes, and it gives you endnotes instead of footnotes. It will insert the endnote number in the main text, and give you a box to type in the endnote content.
Then, when you’ve got a subsequent endnote that you want to refer back to an earlier endnote, use the “Cross-Reference” function. Open your new endnote, put in the reference (e.g. - “Cited in endnote [blank] above”), but instead of [blank], click on the “Cross-Reference” function. Change “endnote” under the “Reference Type” option, and it brings up a list of all the endnotes to that point, in the box “For Which Endnote”. Highlight the one that you want to refer back to, click “Insert”, and it will insert the endnote number.
From that point on, the Endnote function automatically updates the endnote numbers if you insert a new endnote, and the Cross-reference function automatically updates any changes to the endnote number that is cross-referenced in the later endnote.
