This book is really out dated. If you're working in a 3.0 environment this is good for you. If you are ready for Acrobat 4.0, this book doesn't even know it's coming.
If you want to hyperlink from your HTML page to a certain page in your huge PDF document, this book can help. Although it is out dated, it shows you how to use the PDFMark (shows you the old way). Acrobat 4.0 let's you make the marks super easy compared. The stupid part on Adobe (I can say this because I spend a long time on hold with Adobe Techs on long distance) is they don't even know how to hyperlink from HTML to a certain page in a PDF. It is not included in their PDF manual for 4.0. Finally, someone there directed me towards this book.
Don't expect much from this book but it is a must have if you want to find out what Adobe's not telling you. You won't learn about some of the stuff in this book anywhere else unless you have this book. Or, until Adobe gives us all of the details in their user manuals. Hint hint.
