I have used Calibre for years (app. 1300 books) and I have an old Sony Prs-T2 with app. 100 books on it. Now some time ago I lost my hard drive on my PC and backup didn't have all my books on it (my fault). I have recovered most books but I have about 20 books on my ereader where I can't find where I purchased them from and I don't want to have to rebuy them. Now I thought that some years ago I could upload to Calibre from my device. All my books are epub. Any suggestions on how I can upload these books. Many thanks
