As usual Adobe's Classroom in a book series is the best. If you are new to Adobe, this series of books will take you from being a beginner to havein experience using most of the software's functions. If you then follow this book's training and use the skills presented within the book you will most likely develope the skills of an intermediate user. There are 14 lessons included in the book and one bonus lesson on the disk for a total of 15 lessons. The book is virtually the same as the CS4 version except it was updated to include the new tools that come with CS5. Therefore, if you are familiar with Indesign CS4 you could simply go to the Adobe website and pick up the skills for CS5. We have both versions and did not mind getting the new book because we like the lessons having the CS5 features already built in for our new people that need to learn the software. The bottom line: the Adobe Classroom in a book series is the best training series of manuals we have ever seen and we have been in the business of computer aided development for over 30 years.
