Well, I see in a post from 9-13-2010, Isherwood writes:
I had a number of books in Calible from Baen free library that had bad author data or even no author data when pushed to the Kindle. Even after updating meta data in Calibre it wasn't right on the Kindle. The problem is that the Calibre metadata isn't used by the Kindle, it uses the author field in the MOBI file. Its author sort uses expects the string to be in the format "lastname, firstname" (not the space after the comma needs to be there).
I tried using Calibre to convert my books from PRC to MOBI and that helped the ones with no author at all on the Kindle but now the sort order was wrong. I had the Calibre author name set as "Firstname lastname" and author sort as "lastname, firstname". The trick was in checking what was in the MOBI files using the reader window in Calibre and viewing the book properties. It had the MOBI author field as "firstname lastname".
OK, so that is useful to know: Calibre metadata isn't used by the Kindle (?). Rather, the Kindle goes off something internal to the MOBI file. Where in the "reader window" can you view the "book properties"? (I do see the author's name in the text of the book, but I don't think it got changed from "Jonathan Swift.")
Thanks!
