Use the steps below to create links, add links to other parts of the same book, or link to another book in iBooks.
Create a link
Add links to other parts of the same book in an HTML Widget
Links within the same book in an HTML Widget use a standardized format: ibooks://#link type(content number).
- ibooks://#: All links within the same book begin with ibooks://#
- link type: The type of content you're linking to (page, chapter, or figure type)
- content number: The number of the content type that you're linking to
- To link to page 10, use ibooks://#page(10)
- To link to chapter 5, use ibooks://#chapter(5)
- To link to chapter 5, section 2, use ibooks://#chapter(5.2)
- To link to Gallery figure 2.2, use ibooks://#gallery(2.2)
- To link to Review figure 1.3, use ibooks://#review(1.3)
Add links to another book in iBooks
To link to another book in iBooks, you need to know the book’s asset ID. Find a book’s asset ID by going to its iTunes Preview webpage and checking the number in its URL. For example, in the URL https://itunes.apple.com/us/book/e.-o.-wilsons-life-on-earth/id888107968?mt=13, the asset ID is 888107968. A link to this book would be ibooks://assetid/888107968.
If the other book was created with iBooks Author, you can link to a specific location in it by using the format in the "Add links to other parts of the same book in an HTML Widget" section above. Just include the asset ID in the link. For example:
Linking to a specific part of a different book is only supported for non-ePub format books created with iBooks Author. If you use the asset ID of an ePub and specify a page number, the ePub will open, but not to the correct page. You can also use links that include the asset ID in other apps, such as Mail and iTunes U, and the links will open in iBooks.
