I have frequently purchased this book as updated issues are released. It categorizes the companies out there in appropriate categories and by number of employees. You also get website addresses as well. Occasionally the infroamtion becomes a bit outdated but in these ever so rapidly changing times, its hard to blame the publisher. The section on Temporary/Permanent Agenices is quite extensive but probably needs to be organized a little better. None the less, this is a good series that can help most job seekers.
