Hi all, it's nice to find here a subcategory on iBooks. I think that iBook Author has made a great change in the way the books can be made. The opportunity to use media and interactive elements in a book (and not an app) is a key component. There is a book on memory training I'm happy to present. There are a lot of books on memory training, but two things make this one special: 1) it is based on techniques used to prepare Intelligence Service officers; 2) it includes interactive exercises. The book is short, so I would advise everybody to read it - you will find most practical tips on how to improve your memory! The book is available in iTunes. *I will highly appreciate any comments. Currently we are working on an extended version and your remarks will be very valuable.
