A new name is not the only thing iBooks got in the iOS 12 update for iPhones. In addition to simplifying the name for Books, Apple added a wishlist to its reading app so you could keep track of all the ebooks and audiobooks you read in the bookstore.
Oddly enough, in fact, Apple removed the wish list on the App Store in iOS 11, which means you can track apps and games you want to buy with notes, reminders, and other apps. So it's quite surprising that Apple has added a wish list for the bookstore. Could that mean it's coming back to the App Store?
Even though there will be no wish list on the App Store in the near future that is found in iOS 1
Add books from the store to "Read"
When you tap an eBook on the Books tab, an audiobook or any of the formats in the "Audiobooks" tab "Read Now" or via "Search" you will see a new "Want to read" button with a plus sign that appears below the description of the book below.
Just tap on "Want to read" and the article will automatically be added to your list for later. You will know that it was successful by displaying the command prompt, then by checking the box "Want to read"
Even if you have an e – Book or audiobook from the shop, regardless of whether you paid for it or it was free, the item will automatically be added to your "Want to read" list (whether you like it or not). There is no setting to disable this.
Adding books from your library to "reading"
If you have books in your own library that you should not forget to read, you can add them to your "Will you read" collection as well. On the Read Now tab or Library tab, tap the ellipsis (•••) after the book you want to add. Then select "Add to Read" in the popup.
Alternatively, on the Library tab, tap Edit on the top right, and then tap each book you want to add them all at the same time. Once they are all selected, choose "Add to …" at the bottom, then "Do you want to read" from the list of options.
To list your "Do you want to read" list, you can go to the "Read Now" tab. Scroll down and you'll see the section right there. Tap Show All to see the full list.
