Hi to all,
Reading with big interest your replies.
My paper library is 2166 books for now, and Porto DB seems to handle that very easily, without ads, perfectly offline... well, the only glitch is the covers.
As most of you advocate for calibre Companion, I will give of course give it a try.
And following DavidFor advice, I will contact porto DB developper to try and insert the pics in the csv file.
Of course, I will keep you up to date of my efforts
Regards
François
