1. If a book has a compiled title (Sammensatt tittel) each of those will be concatenated with ; and used as title
2. If it has an extended title the title will be: Main Title : extended title
3. If it only has a main title: Main Title

The title on individual files in the zip file is prefixed with track number, eg: 01. title.
