I’m working on a ePub from the Anglo-Saxon Poetic Records HTML files, and need to create a new ePub after updating the HTML. When I do this naively, the new ePub reflects the old HTML. The documentation says
“If you want to edit the input document a little before having calibre convert it, the best thing to do is edit the files in the input sub-directory, then zip it up, and use the zip file as the input format for subsequent conversions. To do this use the Edit meta information dialog to add the zip file as a format for the book and then, in the top left corner of the conversion dialog, select ZIP as the input format.”
That seems to assume you’ve used the debug option and want to tweak the intermediate output. (It also seemed to lose much of the structure, e.g., the output started with Beowulf, not the transcriber’s comments and table of contents.) Am I missing something?
