Blocking Spam & Spyware For Dummies is a reference. That means you're not expected to read it, starting with Chapter 1 and eagerly turning pages late into the night until you reach the exciting conclusion. In fact, let us tell you the end right now: The butler did it - that is, if the butler is an annoying spammer in his spare time, running the operation from a laptop in the basement. The pages of this book are what computer geeks like to call "random access." You can open up to any page you like and start reading there. On the other hand, choosing pages at random seems like a slow way to acquire the information that really interests you, so . . .
Use the Table of Contents to find the chapter or section that you're looking for. If you run across a term that you haven't seen before, check out the Glossary at the back of the book to explain geek speak. If you have the book open and are feeling lost, look up at the top of the page, where you'll find a running head, telling what chapter and part of the book you are open to. If you want to find information on particular topics, troll the index and turn to the page(s) indicated. Dive in and out of the chapters and Glossary in whatever way makes sense to you. It's your book, use it the way that works best for you! (Except for propping up the corner of your couch. For that, use Home Maintenance For Dummies, by James and Morris Carey, published by Wiley.)
