Shelves

Your TBR shelf is created automatically. You can add custom shelves (Favorites, Currently Reading, etc.) by clicking "+ New Shelf." Deleting a shelf removes the organization, not the books—they'll still appear in All Books.

Book actions

• • Read/Unread — Click the green badge to toggle
• • Owned — Click the blue badge to mark books you own
• • Notes — Add context like "Recommended on Fresh Air"
• • Shelves — Click "+ Add to shelf" to organize
• • Delete — Removes from all shelves

Marking a book as read doesn't remove it from any shelves—it stays where you put it until you move it.

View modes

Grid view shows covers with flip cards for details. List view is more compact with everything visible at once.

Why isn't my book being found?

Some books aren't in Google Books. Try using the ISBN from the copyright page instead of the back cover, or try the other format (ISBN-10 vs ISBN-13). You can also search by exact title and author.

What if I text the same ISBN twice?

Duplicates are detected automatically. You'll get a confirmation that the book is already on your shelf.

Why are my barcode photos not working?

Good lighting helps. Keep the barcode in focus, fill most of the frame, avoid glare, and make sure the entire barcode is visible.

Why can't I send a photo of the book cover?

Reliably extracting title and author from cover images is surprisingly complex—there's a lot of variation in cover design. For now, we're focused on features that work reliably. Once the core experience is solid, cover recognition is on the list.

Can multiple people use the same phone number?

No, each phone number has its own library. This keeps your reading list private.

Why is the cover image missing or low quality?

Cover images come from Google Books. Older or less common books sometimes don't have high-quality covers available.
