Query: Where's the Beef???

I use this text in a college course I teach and I would give it less than a C. The authors attempt to cover a wide range of material, but they fail to correctly present critical material even when informed of their mistakes. The book does contain links to useful web sites and is current on many of its topics. However, on the subject of diversity and EEO - they need to stick to the facts and not what will sell books. Too many errors for a text this costly.
