If it happens to be that you’re not importing your text with endnotes already defined … that is, if you’re creating everything inside InDesign … then I find the Numbered List and Cross Reference solution works really nicely.
I’m really impressed by InDesign’s flexibility in allow you to define new “Cross Reference Formats”. Currently the list contains 9 items, including the “Paragraph Number” option which I would use in this example. However … you can ADD to this list, and in doing so, you can create an “Endnote” format, which you can base off of the Paragraph Number format, but then add your own Character Style definition.
Thus, my Cross Reference Format list now reads (notice the “Endnote” as the new item in the list):
Full Paragraph & Page Number
Full Paragraph
Paragraph Text & Page Number
Paragraph Text
Paragraph Number & Page Number
Paragraph Number
Text Anchor Name & Page Number
Text Anchor Name
Page Number
Endnote
Anne-Marie wrote an excellent article on “Creating a custom cross-reference format” in March 2013. The 14-minute video on Lynda.com I found captivating … demonstrating the amazing flexibility natively built-in to InDesign.
I can’t wait to sink my teeth into Cross Referencing!
