Show surname first in the author's name

[Buhaj]

Is there a way to set metadata for authors in a way where surname will be shown first? Or would I have to change it in Calibre before sending a book to a device?

Reason is I want to be able to effectively search files by author, and by default KOReader is listing them based on the first name.

KOReader shows the metadata as is.

If you need to sort the books by the author's last name, here is the user patch:

Different countries and languages have different rules for first and last names.

I think a sorted list should use the corresponding "file-as" properties (meta refines), respectively.

Since these (like the author/creator, for some reason) are optional, the publisher (or you, using Calibre) must have stored them in the EPUB in the first place.

Wouldn’t know how other (non-EPUB) formats store this information, though.

In any case, the correct sort order cannot simply be "guessed" by using blanks or commas and juggling parts of author names around.

Calibre also makes an imperfect job out of it in case of multiple authors (it ain’t easy, really!), but it at least stores an "opf:file-as" property:

    <dc:creator opf:role="aut" opf:file-as="Buckell, Tobias &amp; Klecha, Dave">Tobias Buckell</dc:creator>
    <dc:creator opf:role="aut">Dave Klecha</dc:creator>

Here is an example of another EPUB, not processed by Calibre:

    <dc:creator id="epub-creator-1">Matthias C. Hormann</dc:creator>
    <meta refines="#epub-creator-1" property="file-as">Hormann, Matthias C.</meta>
    <meta refines="#epub-creator-1" property="role" scheme="marc:relators">aut</meta>

So the best approach would be "fishing out" the "file-as" properties. But what should a reader do if none such were given in an e-book? Use the creator name instead (non-sorted)?
