Mijksenaar and Westendorp achieve much of their effect from the vibrant colour reproductions of instructional design with which the book is packed. Every page is a visual treat. There's also an interesting historical overview which shows the presentation of instructions going from realistic photos or drawings of whole objects in the nineteenth century, to more recent depictions which tend to focus on specific parts or functions. The examples they give are so wide-ranging and interesting that I sometimes wished they had stayed longer on any one, providing a more extended analysis, rather than flitting so swiftly onto the next after a few brief comments.

However, applying the principles they espouse to the book itself reveals a weakness as far as the serious sector of their potential market is concerned. Some pictures have explanatory captions, whilst others do not; and on the whole, rather too much space is devoted to visuals and too little to their textual commentary, which for the most part is tantalisingly cryptic. In addition, they don't always make a clear distinction between the good and bad examples, and I was disappointed that they didn't provide a bibliography, because the book is obviously based on a lot of research. They also make little distinction between simple diagrams produced for the lay user and those expanded technical illustrations of cross-sections through a car engine which are produced for engineers. But then, this variety adds to the book's visual appeal. I was yearning for more analysis, but read it with a permanent smile on my face.

This is a lively and refreshing publication which will make anyone reading it intensely conscious of instructional design. The text suggests that their examples are drawn from an archive of materials which has been built up over thirty years, so I hope that their next publication provides a more extended analysis using similar examples, but without sacrificing any of the graphic zest which makes this book so attractive.
