books missing from calibre app
My calibre app shows books in my calibre library, called New Calibre library on the desktop of my Mac. But when I look in that desktop folder, there are books which I have downloaded which do not show up in the main calibre app. I have used other calibre libraries in the past, but Have no idea why there are some books missing and am not sure how to add them to the main calibre database. Please advise!
