Use the Address Book like a phone book and information center for your addressing needs. The Address Book can store names and addresses, e-mail addresses, phone numbers, and more. You can also dial the phone from an address book if your computer is connected to a modem or to a call center that supports computer telephony.
You can create multiple address books for your personal use, and you can share these address books with other users. Open address books are represented by tabs in the main Address Book window. You can display one address book at a time.
You can also use Lightweight Directory Access Protocol (LDAP) providers to access address books on the Internet.
