I am currently writing a non-fiction book which I intend to self publish. Regarding the citations and references, I intend to list them at the end of the book as endnotes and have decided to organise them by chapter which means the numbering will reset every chapter. E.g. Chapter 1: 1, 2, 3; Chapter 2: 1, 2, 3, etc.
So, what if I cite the same source multiple times across different chapters? Do I have to continue to cite them again in my endnotes under each chapter?
