Hoping to find some experts out there with long documents in InDesign who might know something about how to construct text files with markup for footnotes and indices that will import into InDesign. If that's not possible, what is the easiest way of dealing with the construction of footnotes and indices in long documents. I'm doing most of the writing work in LibreOffice and expect to save that out as text files. I would hate to have to start from scratch building those elements in InDesign. I expect to have more than one index as well as more than one table of contents for a historical piece of work going well over 100,000 words. I'm familiar with the markup used in Wikipedia for building references and re-using those references by name as well as referencing other articles, etc. Something like that would be really nice. My Google Foo completely fails me, and it doesn't seem to be the sort of thing that ChatGPT can answer. Thank you, Chris Hoogendyk choogendyk at earthlink.net
