The ONLY reason to use mobi these days is because that is all Amazon will let you email to your Kindle.another Amazon who-knows-why quirk.Īfter-thought: But since you have done all that work already, you might try doing a mobi-to-mobi conversion, after editing the metadata. It's an old format and azw3 will give you better appearance and styling opportunities. Then, after the metadata is in the book itself, convert to mobi, if you must.īest of all, just forget mobi. If these are not on your menu, you can find them in Preferences and put them there. (Embed Metadata will do the textual metadata, but not the cover.) So to fix your problem, edit the metadata on a copy in epub or azw3 format, then run Polish (which has various settings and will let you update the cover and all metadata in the book file). So changing metadata on a mobi file is not going to get it into the book (but see the last paragraph below, an after-thought). Mobi will not.you can't edit a mobi file, and it stores its metadata in a different way anyhow. To write it to the book file itself, you have to do one of several things: run the Polish function, or run the Embed Metadata function, or convert the book.Įpub and azw3 books are editable in Calibre, and will respond to Polish and Embed Metadata. As you have discovered, the metadata you change in Calibre only initially affects the external opf file stored in the Calibre library.
