Hello, I'm sure this has been asked before but I really can't find an answer. Anyhow, I've got about 1400 ebooks and PDF's in iTunes on my Mac and in iBooks on my iPad/iPhone, but I want to migrate to Calibre on my Mac with Shubook or Marvin on iOS.
I've been able to export all ebooks from iTunes into one single directory which I can easily import in Calibre, but without metadata. Also I'm able to get a listing of all ebooks with some metadata from iItunes into Calibre, but I don't know how to match those two together. I'm not looking forward to fix all metadata by hand

Anyone an idea to fix this??
