Are the current mobi at PG in KF8 format? (not only the current ones, also the legacy ones) If so, is the PG epub in KF8 equivalent to PG epub, or equivalent to the old dumbed-down mobi?
We currently have a mix of old and new. The new files actually are a mobi fork and a KF8 fork jumbled together. Amazon introduced the KF8 fork of Kindle files on the sly. Kindlegen was producing KF8 files way before Amazon announced the new format. PG always used kindlegen to produce Kindle files out of epub. So we can say PG was producing KF8 files even before Amazon announced them. I'd have to research which version of kindlegen introduced the feature. PG always used a fairly recent version of kindlegen. You can easily tell by the file size: If the Kindle file is huge compared to the epub file, then it contains a KF8 fork. -- Marcello Perathoner webmaster@gutenberg.org
