So I'll be typesetting a 5 odd volume work in the upcoming months, each volume will be a minimum of about 400 pages, with, obviously loads of chapters and sub-chapters.
My question is about the best way to organise such a large document so as to be able to shuffle chapters or sub-chapters around if the need arose. Should I just make each sub-chapter a different section or actually make each one a separate file? If I kept each volume together in one file with lots of sections, would it still be easy for me to move sections at will without any headaches? I would also want to convert the completed volumes into an EPUB format.
