As a newbie, I used Calibre Get Books to find which retailer I should choose to buy an EPUB version of a book I wanted. I found it in the Kobo store and used the link to buy it. Question now was how to download to my PC, so I installed the Kobo desktop and sync'd my book.
The question now is how to add the ebook to my Calibre library when I don't know the location of the Kobo ebook.
Can anyone point me in the right direction as the Calibre FAQ's and online help don't cover this topic at all?
Any transaction with the third party is outside of Calibre's remit.
