Do not buy the first printing of the APA manual, 6th edition under any circumstances. There are errors on eighty (80) of its pages. How outrageous for a manual on writing style! As of 10/20/09, APA refused to exchange their error full copies with corrected second printings. Despite the fact that the list of errors goes on for 7 pages, the Editorial Director of APA books stated "there are no errors that impede using the manual with full confidence." Many of the errors are in the sample papers -- a part of the manual so many of us use as an important reference. The abuse of power that APA is wielding over students required to purchase this book for classes, along with graduate students and professors who must write in this style for journals is alarming. APA goes on to state that with its 80 pages of errors in this edition that "it is within my control, as a true expert who has been intimately involved with each stage of this project, to verify for you without hesitation that the first printing is correct, accurate, and fully functional." As a Professor, when I grade papers, I say to my students that 3 APA errors will get them docked 1/2 a letter grade. If I were to grade this APA manual, it would not only get an F, there aren't enough letters in the alphabet to go low enough for the number of errors it contains. Meanwhile, APA is happy to take everyone's money for the book they know we all have to purchase in so many fields of study.
A formal boycott of this edition successfully led to a second printing in which the errors were corrected. As long as you order a new copy, not a used one, you should be safe. If you buy a used copy, make sure that you do not get a first edition -- it is a complete waste of money.
