How do Grab and Pass work, and can I undo them?

Open any book from your scan results and you'll see two buttons.

• Grab It is for books you're buying. They go into My Books → Grabbed, so you have a record of every find and where you found it.
• Pass is for books you're not interested in. Spines won't mark them Worth Grabbing again.

Both teach Spines a bit more about your taste, so your recommendations get better as you go.

Undo a Grab

1. Open the book, from your scan results or from My Books → Grabbed.
2. Tap Grabbed!. You'll see Removed from Grabbed.

Undo a Pass

There's no un-pass button yet, but you can reset a book in two taps:

1. Open the book from the scan where you passed it.
2. Tap Grab It, then tap Grabbed!. The book is back to normal.
