Option 1: Searching
The search bar in the top right corner is not just for finding out what is in your library.
For the most specific results, enter the ISBN.
For more broad results search by Title or Author.
To limit search results to only one category change the Type.
Expand your search to see all items by one Author.
Now to add an item simply press the + next to the result you own or drag and drop the item onto your shelf. You'll know instantly you added the item successfully because it will shoot to the top of your list and in the Amazon search results it appears with a big red Owned stamp.
Voila! Now you can start building your library using our search bar. Next time I'll explain how to add items using your webcam or handy dandy iOS scanner app.
