i was going quietly crazy yesterday trying to add a book & diagnose why calibre was saying " book already in database - add anyway ?" - when various calibre & windows searches + library integrity checks proved that the book in question was NOT in the database.

I finally figured that the add books duplicate check looks only at title, not at title AND author - surely it should be checking both ?

I was trying to add Resurrection my Ken McClure. I already had a completely different book , also called Resurrection, by someone else.

Any human would immediately spot that the books were not duplicates of each other - can calibre not also spot that in future.
