You can read more about each of the ebooks on our Web site, but in short:

• "Take Control of Upgrading to Leopard" is the latest edition of the title that launched Take Control back in 2003 with Panther. In it, Joe Kissell shares his hard-won advice about the best ways to install, test your installation, troubleshoot problems, get going in Leopard, and more.
• "Take Control of Customizing Leopard" provides a tour of new and revamped features in Leopard by the ever-opinionated Matt Neuburg. Matt demystifies Time Machine, shows you how to use Spaces effectively, and explains why Spotlight in Leopard is so much improved over Tiger.
• "Take Control of Users & Accounts in Leopard" describes different types of accounts in Leopard, which ones are right for the different people who use your Mac, how to share files between accounts, and what you can limit with new features in Leopard's parental controls. Kirk McElhearn also explains how to create and use a troubleshooting account should problems crop up.
• "Take Control of Sharing Files in Leopard" makes file sharing easy between two Macs, among a mixed-platform office workgroup, or between far-flung computers on the Internet. Wi-Fi guru Glenn Fleishman explains each of Leopard's file sharing technologies and helps you connect to file servers from a variety of major operating systems.
• "Take Control of Fonts in Leopard" explains everything you need to know about how fonts work in Mac OS X and what has changed with Leopard. In particular, veteran Mac author Sharon Zardetto looks at Leopard's new and updated fonts, along with Leopard's new font activation capabilities, font previewing via Cover Flow, and font sample printing.
