Sorry that this review is in English: my written German is awful.
I was a bit disappointed by this book. The intended audience is unclear, and it contains a lot of irrelevant (and hyped) information. Also, it doesn't cover XML-based publishing.
Cross-media publishing is interesting for many audiences: printers, publishers, multimedia companies, web agencies, large corporations, etc. The author doesn't identify the different types of CMP applications for these various audiences: publishing a daily newspaper has totally different CMP characteristics than publishing stockmarket reports at an investment bank.
Also, the book is filled with a lot of irrelevant information. Chapter 1 explains the history of printing technology (starting with Gutenberg). Chapter 2 contains a section about datamining. Chapter 4 describes the HTML tags in detail. Chapter 5 explains how Adobe Acrobat works ('which buttons to push'). Chapters 8 and 9 describe CMP products with a lot of detail (how to operate these programs). It's a lot of details, without providing any insight into real CMP challenges.
In my experience at a content management vendor, I have encountered some real CMP challenges. I was hoping that this book would at least give some ideas for solutions. But my paradigm for CMP is based on XML. From XML you publish to the different media types. This book contains exactly 1 page about XML.
If you work at a printer or multimedia company and you don't have any ideas about CMP publishing, you might want to read this book as an introduction. Otherwise, read a book like 'Content Management mit XML' by Rothfuss and Ried, although it is more technical and somewhat light on CMP issues, but at least it gives a thorough understanding of a medium-neutral publishing process.
