The title of this book is well chosen. It is a book about design but its target is not the design professional but the everyday person who at the minimum needs regularly to create documents of some form or another. There are many who use a word processor that has some sort of page layout capability - most now do - or who are creating longer documents that demand use of a full-blown page layout program. Adobe's InDesign and QuarkXpress are two of the most popular, although there are others which are more affordable, such as that offered by Serif.
When laying out a page, there are many considerations including typeface, font size and colour, placement of titles, subtitles and headings, size and location of images and much more. It is complex and few will get it right every time. This book takes the reader through the process and includes some specific advice for the users of some of the most-used software which, with relevant modification, could also be used in some other.
Although there is some technical terminology used, the book is not intended to be overtly technical and, for most readers, it is at about the correct level for its audience. However, by trying to embrace 'design' in a broader context than most non-professional users would ever likely need, that is its minor short-coming. Robin Williams, a female rather than the comedy actor of the same name, is a designer by profession and should therefore have plenty of first-hand knowledge and experience to pass on.
I actually bought the first edition when it came out some years ago, and I found it quite valuable. This is much updated and includes some of the more recent features that have been introduced into software since the first edition was published.
Recommended, although there are parts of the book that few will actually need.
