To view all your contacts in a section of the alphabet, click on the section you want. For example, clicking "Ed-Ho" lists all your contacts that fall between, say, Edwards and Hong. The actual section breaks you see will change depending on how you sort your contacts (First Name, Last Name or Email), how many contacts are in your Address Book and how many contacts you've opted to view per page.
Search your contacts by typing a name (first, last or nickname), email address or domain, or a fragment in the "Search Contacts" window in the upper-left corner of your Address Book. Matches are displayed alphabetically.
Pick a category from the left side of your Address Book to view your contacts by category. You assign contacts to categories when you enter contact information, and you can create your own categories. Learn more about categories here!
In any view, sort your contacts by using the handy pull-down menu once you click on the "Sort By" link. It's on the bottom of the page, near the "Check All/Clear" link. See it? Just use the pull down menu to choose from "First Name," "Last Name," or "Email".
You can view up to 100 contacts per page. Your account's set to 50 by default. Here's how to change the setting if you'd like to view more, or fewer:
