All of my books which are published by Sage are accessible electronically.
Amazon's free Kindle e-reader can be used to view the content of the books.
It's available for iOS, Android, Mac, laptops and computers.
You can then purchase the Kindle edition of any of my books and download it to your device.
The book will go into your Kindle 'library' for you to open and read.
It should allow you to convert the text to audio, to change sizes of text and images, and search for key words or phrases.
