[.ca] Carl Young's Adobe Acrobat 6.0: Getting Professional ... (ISBN 0072231386)

The Essential Guide to Acrobat 6.0:
Unlike many books in this category, Carl Young's book is not a rewrite of the Acrobat Help file. He lays out the most common mistakes creators of PDFs make, and then provides step-by-step solutions. Highly recommended.

If you must only have one Acrobat 6 resource, make it this!:
Every graphic designer should own this book! Designers constantly send PDFs that are waaaaay to big, or have missing fonts to my small marketing/pr firm. I may buy copies for every designer I work with.

Best PDF Book I've Seen:
I'm one of those people who buys every software book on the market. I've looked at lots of books on PDF. This is the best yet. It's practical and tells me how to avoid making the most common mistakes in creating a PDF. I wish the rest of my colleagues would read this.
