I had fun the past few weeks using iBooks Author to create a book for iPad about travels in Spain this May. Even though it was designed for textbooks, people have now used the free software to create thousands of multimedia books on ordinary topics such as how-to, travel, language learning, art, children's books, etc. While there was a bit of a learning curve the first time, I hope it will be easier down the road. There are good instruction manuals free to download in the iBookstore. You can see all the multimedia books made with iBooks Author in the Features section in the iBookstore. Maybe you'll make one yourself!
Meanwhile, check out my free book, MAY DAYS IN SPAIN at either of these links:
