Reporting Services Book
Yesterday I read Anthony Mann's book "The Rational Guide to SQL Reporting Services". I quite enjoyed it. Although it's brief, I like the short punchy style of this series of books. They just tell you the main things you need to know to get started with a topic and at a pretty low cost. The last Rational Guide I read was Roger Wolter's Service Broker book, although it had more meat in it.
Anyway, Recommended if you want a short sharp introduction to SQL Reporting Services!
