I'm new to creating ebooks. I have mp3s and mp4s that I want to include in my epub so I started off making an epub v3. I started with using Sigil to create my file but I'm wondering if it was a mistake.

  • I've opened a bunch of epubs that I already have with Sigil and noticed that they are filled with Calibre references.

  • Missing meta data seems dodgy to add with Sigil. It isn't very intuitive and I've been adding the fields manually in my Content.opf file.

  • There isn't any toc.ncx. Even after generating a table of contents it doesn't create a ncx file. TOC is still empty in my epub reader (Marvin).

Perhaps I'm just new to all this, I hope my question isn't too opinion-based or preference orientated, but would I have had an easier time with Calibre or some other software? Will I be creating issues for myself by starting with Sigil now, if I want to switch over later?

    Better to ask how to fix each issue in sigil. Re the calibre references are you sure you have not opened anything in calibre – mmmmmm Jul 16 '20 at 9:53
  • @mmmmmm What I meant was that, many epubs that I've previous purchased or downloaded are filled with Calibre references. – Mou某 Jul 16 '20 at 10:53
  • Quite possibly converted from another format eg a set of html files or a kindle format or m I crosoft word so not saying they use calibre as an editor – mmmmmm Jul 16 '20 at 11:17
