I recently shared an iOS Shortcut for scanning citations directly from the barcode of a book. Handy as it is, I have another shortcut I’m getting a lot of mileage from when I write on my Mac. Both Zotero, and Bookends 1 can add references to your library directly by scanning different metadata, including any book’s ISBN. You can obviously search for the numbers, or type them out by hand, but this little trick can add items to your library by using an iOS device as a scanner.
The shortcut works by scanning the ISBN from a barcode of any book and copying it to the clipboard. If the Universal Clipboard is working properly, the ISBN will become immediately available on the nearest Mac to paste into Zotero, or Bookends. I have also set it to copy the number to my clipboard manager in case the universal clipboard fails, as it does far too often 2.
This version of shortcut is configured to use my favourite clipboard manager, Copied. You could also use the equally impressive Paste, which is included with Setapp. Or any other app with a URL scheme that uses iCloud sync, like Gladys or Yoink. You could even use Apples own Notes App in a pinch.
