Because it's meant to fit into a larger regime of practice and experiment, this book is skinnier than pretty much any of its competitors. Don't let its compact size fool you, though. This is a thoroughly researched, carefully organized guide to everything Microsoft expects you to know for the four main MCSE exams. It's very dense--with lots of tables, lists of options, and procedures--but has enough commentary to help you get concepts like data-striping and database-sizing straight in your mind. Each chapter concludes with a sample test (with answers) and a "Highlighter's Index" that lists key facts in super-concise form. --David Wall
