Merge docs, putting all endnotes at end of doc, but preserving endnote numbering for each chaper

IF each chapter contains only one Section, and you insert each chapter into a separate Section (insert a Section Break), then after combining the documents, if you go to the access the Footnote and Endnote dialog and set the options as shown below, I think that the Endnotes will be relocated to the End of the document with their original numbering retained.

If each chapter contains multiple Sections, then, you could run the following macro on each of the chapter documents before combining them and the manually copy and replace the "textnotes" from the end of each chapter to the end of the document (in the appropriate order)

' Macro created 29/09/99 by Doug Robbins to replace endnotes with textnotes at end of document

' to replace the endnote reference in the body of the document with a superscript number.
