Query: Too little for too much

This book is probably useful to a novice. It is long on simple minded "lessons" that tell you in excruciating detail each and every button to click, but comes up short on providing any depth. My copy was marred by having several duplicated chapters. If you have any serious interest in Acrobat, buy "Acrobat Pro" by John Deep and Peter Holfelder (John Wiley and Sons)
