No, I drink Earl grey daily, but I didn’t even knew (until a couple of moments ago) that it was Picard’s drink. I first had one on a train in Russia, and fell in love with it. The ones I have today are not the same as that one but still very good.

That’s a solved problem, the answer is Calibre. If you want a nicer interface and some other fluff you can install calibre-web as a frontend for it. Calibre-web is very interesting if you have a Kobo e-reader because you can configure it as your store and get the books you add to calibre to magically appear on the e-reader with a nice download button next to it.
