David wants to know if he can listen to an audio book with his iPhone as well as his Android phone. Leo says he should, unless Apple does something different to them when buying them off iTunes. But if the audio book is from Apple's iBook Store, it's copy protected with the ePub format. He would need to strip it in order to play it on another platform. There are programs and plugins that do that, but they tend to be fly by night. TunesKit has one called iBook Copy for Mac. It has a free trial.
Mike has written an ebook and he wants to know if he should copy protect it. He's going to be giving it away for students to see if they like it. The LA Sparks want him to copy protect it. Leo says he's not a fan of DRM because it simply doesn't work. He needs to figure out a way for a limited amount of students to be able to access his book as part of a 'beta test.' Leo says he'll need to have an authentication server to verify it. Lock Lizard is one option that uses an open source DRM scheme.
Larry's wife wants to back up her Kindle eBooks onto an SD card to read on another device. Leo says that Kindle uses MOBI as its file version, and it can only be read by Kindle. She'll need to convert the files to ePub, which is a standard format. Leo likes Calibre for that. If she uses the Kindle app, then it's no problem, and she can just install the MOBI files to that other device. She'll need the folder structure first, so she should download a new book on the new device with the Kindle app.
Noberto is a retired scientist turned self published author. He wrote and published his book through Amazon's Create Space and wants to expand to Apple iBooks. Leo says that using Create Space means he's stuck with just Amazon, and that really is the biggest place. Getting it on Apple iBooks can be done in a similar fashion. Apple offers iBooks Author for free. Apple will let him do self published works, but the key is to get it in the right format (ePub).
