I've now used Acrobat for a number of years and have, for the most part, been able to figure out what I needed to do. I recently bought a new scanner (which is not yet available on Amazon) and have come across several problems while converting documents to .pdf files. Due to these matters, I thought I'd finally spend the money to buy this book to fully learn all of Acrobat (I have Acrobat 9 Pro) features. To say that I'm disappointed in this grossly overpriced book is an understatement. Much of the book is devoted to materials that do not need to be dealt with (as they're so basic) or on flashy (no pun intended) elements, such as 3-D animations and other not-so-important features that I suspect most users could care less about.
To make matters even worse, the book instructs readers to examine the help files that come with Acrobat for information (if these help files were useful, I wouldn't have needed to buy this or other books). Then there's the problem that some features are not covered in detail at all - as I mentioned earlier, I'm trying to use a new scanner and the OCR functions on Acrobat. Less than a full page is devoted to that topic and essentially nothing helpful is provided (yes, I already know how to press the button on the scanner - something that this book tells readers to do). Nothing at all is mentioned about the new feature in Acrobat 9 about "ClearScan" - the function that replaced Formatted Text & Graphics found in older versions of Acrobat. While I finally figured out what "ClearScan" was by searching the Internet, I still can't figure out how that is used to with the TouchUp Text tool (which seems to work much differently in Acrobat 9). While the results of "ClearScan" seem to be very good (at least as far as I can determine at this time), this book says absolutely nothing about it.
Overall, the book does provide some good information, but one must wade through pages/chapters of things that need little or no explanation in order to find it. While this book is beautifully published (nice paper, good graphics, etc.), it is even less valuable than Acrobat's insufficient help files (for example, ClearScan is NOT covered in any detail there either). I would not recommend this book to anyone who is already familiar with Acrobat - only to those who are true neophytes to the program. Even so, there are too many items of importance that are not covered.
