Finally, an address book that's easy to use, logically organized, with space for plenty of entries per letter, and designed for a social-networking world that forces you to change your password every six months. Are you frustrated that you can't remember the unhackable password you came up with the day before? Tired of hitting "Forgot Password" because your login hints leave you scratching your head? Say good-bye to those sticky notes you've got shingled all over your computer. Most address books being sold today still look exactly like the ones you'd have bought decades ago. But it's a different world now. Businesses and friends require different sets of information. You don't need to know Amazon's street address, nor does your mother's home address require a password. What you do need are user names, passwords, security question prompts, and IP addresses for your business contacts as well as street addresses and smartphone info for your personal life. In creating Address Book for the Twenty-First Century, Frank Stephenson and Eileen Hargaden recognized this. They've separated those very different types of interactions into two sections: "Businesses and Websites" and "Friends and Family." This address book is for anyone who can log onto a computer or who has even just one friend or relative. Perfect for both business and home use.
