This book is laid out nicely, with exercises and thought processes on how to develop effective icons. The author includes examples of icons he has developed for applications in the past, along with his workflow. For example, one section lists the name of each icon (Edit, Delete, Add quotation) and then has sketches of 5 different ideas a piece. This book also discusses why people associate certain symbols with certain phrases, as well as outlining when to use graying, broken lines, arrows, etc. to add meaning.
One shipment of this book did not include the disks, I had to call back and get the disk shipped to me seperately.
