Best of all, you never had to rewind a book. This was the beginning of random access. Iris has taken books one step further. Instead of citing page numbers, authors can cite topic names. Readers can select the names directly from the screen, or from a menu.
Electronic books can ask questions and respond to the answers.
Readers can jump from one topic to another with the flick of a key. Windows can change color and size, and be accompanied by pleasant tones. When you use Iris, the first thing you see is a friendly help screen and a menu of available books. This menu works like all Iris menus. A single sorted column with items that can be selected with cursor keys, or by typing the first letter of the item.
