We usually only index one version of a book and then link all other editions to it. In the Library, you will see the Indexed edition featured, and the linked books listed.
- Click on the link icon to show all other editions.
- To add one of the linked books click on the ISBN.
- On the Book details page for that Book click on the +Bookshelf button.
- Whenever you see this link after a Book title it means it's a Linked edition, click on it to reveal the Indexed edition.
Some books have UK and US versions, we have indexed some of these separately, so you will see two indexed versions. Choose the one that you own. For example, several of Nigella Lawson's books have both the UK and US versions indexed.
