iBooks - drm free epubs and pdf files

[empire01]

I have added a large number of my own drm free epub and pdf files to iBooks and iCloud. Now I would like to take a copy from iBooks of some of my own epub files but can't find them anywhere! Could someone tell me where my ibook files are stored?
Its such a simple question I'm sure others have asked it but can't find any question in the forums. I'm using MacOS Sierra.
Thanks

If you sync between your devices, there should be a space on Sierra storing all your books.
One place I have found on Internet is:
~/Library/Containers/com.apple.BKAgentService/Data/Documents/iBooks
Which stores all your bought books.
Many other files actually sit in the iCloud Drive but hidden. In particular, all PDF are Stored hidden.

Last I checked, iBooks stores your content in a database with human-indecipherable file names.

[doublepost=1478609234][/doublepost]Why they just can't add a iBooks folder in iCloud Drive I don't know. All this hidden stuff is useless. I'll stick with Marvin and the kindle app in future.
Thanks both for your help.
