With the release of iOS 8.4, iBooks on the iPhone can now display iBooks Author rich media books like the MacSparky Field Guides. Hooray!

Often I receive emails from readers asking to read my books on the iPhone. Now you can. The books look great on the iPhone. Paperless, Email, Markdown, and 60 Tips all display in the alternative format (pictured). This allows you to also change the type size. Presentations displays in its original format, which looks great but doesn't allow you to change type size.

Either way, I'm thrilled to have millions of potential new customers. If you've already purchased the books, they'll load just fine on your iPhone today. If you've been waiting for them to become iPhone compatible, today is your lucky day. I'm already making changes to the next MacSparky Field Guide to make it even more iPhone friendly.
