Thanks Ortep for the mobi2mobi suggestion.
I was actually also trying to edit the metadata of some books I got on ebooksgratuit.com, because for some reason most of them don't include the author in the metadata (and a folder with different children's tales books all entitled 'Tales', with no author showin, is not fun).
I was trying to use calibre to do it but it wasn't workin, mobi2mobi is far simpler for this use!
