APA MANUEL fifth edition
The best thing that I ever did was to purchase the APA Manuel.
It has helped me with formating and the proper way to cite in text and referance in APA format. This book is much better than the Diane Hacker book on APA.

Evil But Necessary
This is one of the most cumbersome and difficult to navigate reference books out there, and it is notorious for being so. I highly suggest getting an APA formatting program for writing your papers using this style. I use APA PERRLA myself, and love it. You will still need to refer to the publication manual for your more rarely used reference types, etc. Unfortunately, it's a necessary evil.

For All College Students!
This book is required for all college students pursing a degree in any major. It may not see like the most interesting book to have on your shelf, but is crucial when writing college papers.

It is an essential tool you will be glad you have for reference.

Confusing, and hard to use
I bought this book because most of the internet guides are not comprehensive enough to cover specifics addressed in this book. I agree with other users that say this book lists material on the same topic in multiple places, requiring you to waste time checking around for something you think you remember seeing before. The index needs to be re-done, something I hope they fix for the next edition. Electronic resources are very generally addressed.

good resource
good resource, but consider also getting a more user-friendly book to help with APA, too....you will waste a lot of time looking for information in this one.
