I have huge address books which contain many duplicates, not within the same address book, but across books. Is there a way, let’s say, to select two or more address books, and use the provided “Find Duplicate Contacts”? In this case not “in Current Address Book” TIA 21st March 2019 at 18:30 #2545 CardBookKeymaster in CardBook toolbar, at the top left, click on the hamburger menu, then Tools, then fourth line 21st March 2019 at 19:35 #2547 jssilvaParticipant That was really fast, thank you so very much. Can you believe I had never noticed the hamburger menu? Silly of me, sorry for wasting your precious time. Keep well, the open-source community needs you.
