Hello Chaley, i hope you'll still give an eye to this post...
I built a test library before continuing, then i tried your python script...
And magic ! It works !
Now i would like to be able to do my own little personnal fields, based on your script but i need to learn python a bit, and how to interact with Calibre.
I don't want to bother you with full of newbie questions, so...
Can someone please tell me where to find some documentations, about python oriented Calibre ?
Thanks in advance
