Introduction to the New Mainframe: z/OS Basics by Mike Ebbers, John Kettner, Wayne O'Brien, Bill Ogden (2011) Paperback - Learn IBM Mainframe Computing for IT Professionals & Students

My school finally is getting up to date with information technology. Well, technicallly mainframe computing isn't a new thing! This book is great and it really prepares you for entry level positions. A lot of companies are looking for employees in the younger generation to fill their ranks as the older mainframe guys are retiring. This means a lot of money and a steady job for anyone that wants to reach out and grab it. I recommend buying this book and learning Z/OS!
