Query: Waste of time.

I do not recommend this book unless you have no clue about APA. If, you are somewhat familiar with using APA style in your research papers, do not bother to purchase it. You can glean the same information from the actual 5th ed. of the APA manual. Check with your reference librarian at you college or university. They may be able to provide you with handouts that may actually be more useful. Therefore, I did not find this book user friendly.
